Actionscript 3 :: Parsing A Large CSV File, Dealing With Commas And Quotes
Oct 12, 2010
I need to load in a large CSV file (>1MB) and parse it. Generally this is quite easy to do by splitting first on linebreaks and then commas. The problem is though that some entries contain Strings that include their own commas. When this spreadsheet is converted to CSV, the lines containing commas are wrapped in quotes.
I've written a parser that first escapes all the commas in these strings, then splits it on linebreaks and then commas, and then unescapes the values again.
This is quite a slow process for such a long string, as I need to iterate through the whole string. Does anyone know a faster or more optimised method of dealing with this?
I have a Flash web app which displays user submitted PNG files. Files are uploaded to the server via some API prior to being displayed. I'd like to make sure no "bad" files are served to Flash, where "bad" is entirely unspecific. Is there a way to validate PNG files against the PNG specs (this would catch corrupted files)? Or any best pratice on dealing with untrusted image files? I only need to handle PNG, so JPG, GIF etc. support is necessary. Language mostly does not matter, though I'd prefer Python solutions. This is on a Unix webserver.
In my project, there is a frame(png files) placed on the top of all symbols. After that, I apply mouse click event to the symbols that place underneath the frame symbol, but when I run the the game, I cannot click to the below symbols but only the frame symbol, although the frame is transparent.
The problem is, although the png picture has some transparent area, the mouse click cannot pass through it. Is there solution? Is there anyway I can disable a symbol from being clicked and mouse click event can recognize the symbol placed under it?
A question on naming objects and nameing of strings. A string has quotations "I am a string"......Q.1 If i have a movieclip on stage like an empty movieclip and i wanted to refer to the object in my code as below. As an example my movieclip is called mc1.Do i use 'mc1' single quotes....
I've written some code that takes user input and adds it to some other static text which is then sent to php to be written to a text file. The file is just plain text but has the .xml extension so it can be used as a source of data. Because of the XML content the text has to contain quotes so I am looking for ways to escape the double quote characters with " or using the alternative method of using a mixture of double and single quotes to differentiate content I want in the text file and the quotes that define the boundary of the text string. The code is working but the resultant XML looks wrong, with double quotes being written as " even though I used the double/single quote method, so I'm a bit baffled why this is happening. Here's my code:
[Code]...
All the double quotes are being written as " which is the escape character instead of the actual character - anyone know why this is happening and how I can fix it?
I am using this random code below to choose a quote to display and I want to move the quotes list to a text file, can point me in the right direction I cant seem to get it to work.
Code:
quotes = [Fish are the last to recognize water.","I am my brains publisher.", "Every tool carries with it the spirit by which it has been created.","Curiosity is the mother of intelligence.","Thinking is drawing in your head.","A person without imagination is like a teabag without water.","Realism is a corruption of reality.","Its always better to be looked over than to be noverlooked.","The hardest thing to see is what is in front of your eyes.","The soul has no secrets that conduct does not reveal.","Creativity is the defeat of habit by originality.","Those who cannot remember the past are condemned to repeat it.","If you want to get lucky... it pays to get ready" ,"Realism is the corruption of reality","I'd give my right arm to be ambidextrous.","Music is noise submitted to order by wisdom.","God...invented the giraffe,the elephant,the cat.He has no real style.He just goes on inventing things.","The person you love is 72.8% water."]
I have a 6mb XML file, resetting my script timout in CS4 doesn't help. (it does have some unnecesarry HTML in it I could probably do away with, but that would be the wrong direction I think)I can't even trace it.I am loading it into an :XML object and trying to work with it, but all to no avail.
Here is my Class:
Code: /** User class author: Manaburn
[code]...
The for each loop wont iterate for some reason, but the for loop will, then again, it always crashes me with:
Code: Error: Error #1502: A script has executed for longer than the default timeout period of 15 seconds.
(which as I stated above I reset, but as this is a .as file, I don't think it allows that.)
I want to parse a dae file for getting the texture name. But when I am trying to read dae as xml it read the entire dae file but the problem is that I can't access it's elements
My Code: package{ import flash.events.Event; import flash.net.URLLoader; import flash.net.URLRequest; public class XMLReader{ [Code] .....
In my flash, the socket server returns some xml data that I need to parse, but it seems that the only way to start the XML object is with the XML.Load() which loads an external file, but my XML file is already loaded into a variable
trace("raw: "+msg); msgArea.htmlText += "update remote player loc"; var playerLocXMLOb = new XML(msg);
I am trying to parse data from a user created .txt file and convert it into an Array. This data will eventually be used to output an .xml file or to generate html. The user has no experience or knowledge of XML otherwise there would be no need for this post, I would just parse XML. The data will be set up as a group of items (term and definition, question and answer as well as a type to determine the attributes of the item) like so:
1. How many licks does it take to get to the center of a tootsie pop? a. The world may never know. t. ML
2. What is the square root of 69? a. 8 something. t. SA
I am currently able to allow a user to have an Open Dialog box to open a local .txt file from their computer. I am also able to read the data and trace it via actionscript. I cannot however split the data where I want to into an array. I cannot use '' to split at as the data from the .txt file may sometimes be multi-line for the question or answer.
So I need to be able to; a) split on a number with a . and a space (eg. '1. ') b) split on a-e with a . and a space (eg. 'a. ') and c) split on 't. '.
Here is the relevant code I have so far:
ActionScript Code: import flash.text.*; import flash.net.FileReference; var tf:TextField = new TextField();
[Code]....
I was just trying to hardcode a couple things like splitting on 'a. ' and 't. ' but it only does one split, whichever comes last.
I'm trying to call to a date in an external txt file (losttime.txt).The date is written as: 2012, 1, 09 in the .txt file.I've loaded the txt file and need to calculate the amount of time between that date and today.Right now, I have the date set in the lostTimeDate variable, but need it to call to the date in the txt file instead. I assume this has to do with Parsing the date, but for the life of me, cannot figure it out.Here is my code:
var myTextLoader:URLLoader = new URLLoader(); myTextLoader.load(new URLRequest("losttime.txt"));[code].......
I am loading in a bunch of text (and other data) from an XML file into Dynamic Text Fields on my stage via an XML.load call. Below is one example of one entry of my XML file:
PHP Code: <stillDescriptions><text>Mack Trucks of North America came to us tothem create marketing m
i have a large text file full of several chunks of binary data, each chunk separated by "---"
so it looks like this:
[Code]...
I have loaded the data in an untyped variable. var data:* = URLLoader(event.target).data; so data contains all the text file content. my problem is that i want to parse this text file and put each chunk of binary data into a ByteArray.
any ideas of how i can go about doing that? i have never dealt with untyped variables before so i am not sure what to do. and i don't want to lose the binary data representation by casting (if that happens).
I am totally new to actionscript (barely could set up the IDE environment for Linux). I have trouble parsing an xml file containing some namespaces. All the tutorials and samples i found online are not working for me. the file looks like this:
I got a problem with adobe flash cs4 : I can't launch it normaly and its says that a fatal error has occured.. I really don't know what I must do.. Please, help me.... I've just lost like 3 or 4 files of adobe by trying to reinstall it.
Hey flash gurus. I did a search and while I feel certain this has been covered (and am content to be flamed) I couldn't find the answer here on the boards so here goes...
I fumble/stumbled my way through making a web site for myself and I'm pretty happy with the results. I am sure I did some obscenely newbish things but it works and it looks good enough so I'm fine with it for now except...
It takes a good long time to load the web site which I believe is due to the fact that ALL the pages of the web site are mashed into a single SWF file. I would like - for a number of reasons - to break this into several different pages (not just for size but to make updates less painful).
I'm working on a project currently and need to import a large file FLV into flash. It's not over the 16000 frame issue as I've checked this. I'm in Flash CS4 and have an animation in 1080p res. It will import up to about 4653 frames fine but it will be only part of the complete file. Is there any way around this? We're using this as a cross platform container to alleviate video programs and compatibility issues for training. In the Publish settings we can export for Mac and windows options etc.
I code primarily in PHP and Perl. I have a client who is insisting on seeking video submissions (any encoding) from the public via one of their pages rather than letting YouTube do its job.Server in question is a virtual machine and I can adjust ini settings for max post, max upload size etc as needed.My initial thought is to use a Flash based uploader with PHP on the back end but I wondered if someone might have useful advice and experience on the subject?
I have a mp3 file that is 2:30 long and is roughly 5.5mb. How come when I import the file to my fla library it sees it as being 29mb large. My swf isn't large when I compile the project but the fla file jumps from 2mb to 30mb just from adding this sound file. P.S. This site has been a ton of help with different aspects of my flash project.
I have a very large text file (it's a 270,000 word list with one word per line) which I need to bring into my AS3 code. Importing it via url works just fine - loading it in as a string then converting to an array - no problems.
However, I need to embed it into my code somehow so that there are no external files (for easy distribution). Using a search and replace tool, I've tried several things, none of which have worked including:
Code: Converting to an array: var wordList:Array = ["word1","word2","word3", ...]; Result: crashes compiler too.
The same tests work fine with much smaller sized word lists, but apparently the size of my word list is too large to work. I know flash can handle strings and arrays of this size, because as I said, it works fine when importing the text file via url. I just can't seem to get it to compile it when I embed it into code.
I'm using Flash CS4 for Windows XP SP3.I have a large project (12MB) that was originally created in CS2 (it's an Actionscript 2.0 project) that I have now opened and saved from CS4 (still using Actionscript 2.0). There are many movie clips that use 9-slice scaling in the library. While editing a clip that has a child clip that has 9-slice turned on, that child clip is invisible on the stage. The object is still there, and when I double-click the child clip to edit it, I am able to view the clip correctly, but when I return to the parent movie clip, the child clip is invisible again. When I publish the movie, the child clip appears correctly. When I turn off the 9-slice checkbox, the child appears correctly in the parent again.Any project that I open or create after having this large file open exhibits the same behavior, even if I close the large file. I have to restart Flash to make the behavior go away. If I have a file open before opening the large file, that file is not affected and works correctly.Also, a clip that has nested child clips, one of which is a 9-sliced clip, will be be completely invisible in the parent clip, even if some of the other child clips do not have 9-slice checked. For example:[code]
ParentClip1 has two children. ChildButton2 is one of those children. ChildButton2 has two of its own children, LabelClip1 and BackgroundClip1. If BackgroundClip1 is set to use 9-slice (it has rounded corners), then neither ChildButton1 or ChildButton2 or its children are visible in ParentClip1 (again, when the file is published everything appears fine in the SWF; this happens only in the Flash CS4 IDE).Finally, I can select "Edit in Place" to edit nested elements, but "Edit in Place" is greyed out when I have a 9-sliced clip selected. I can only select "Edit Selected" if I want to edit that, and when I do that I jump out of edit in place mode (though I can still navigate back to the parents using the breadcrumbs).
I am currently working on the largest Flex / Flash Builder 4 application I have ever built. I am acustomed to keeping all of my MXML programming in one file. What are some best practice procedures for keeping large MXML files readable?
I'm sending from a AIR desktop application an image along with some text as a Base64 encoded string. If the image size is around 100 KB the upload works but if its a bigger one ~220 KB I get an Error thrown back after some time. Error opening URL but the url path is correct and can be found.What is wrong with my PHP?
I'm working on a final schoolproject at the moment and the file size is getting really large... Because I might update this project later with more footage, I've already put a lot of code on the buttons which I have put between comment tags for now, so I'll be able to update it later easily.
The max on our project is 10MB, now there is a lot of external footage like sound and video, but still all the flash files together are taking up a lot of space.
Does anyone know if a lot of comments in the code have any effect on file size?
I want to attach a sound file and have several cuepoints that will cause certain movies to play as the sound file plays.I've looked into this and think I'm right in saying that you can't have an external sound file, like you can have an external Flash video file?What would be the best way to attach my large sound file?One way which I thought I could do what I need: create a Flash video file, don't show the video file and just play it... and then use Flash video's cuepoints.
