IDE :: Formatting TextField Populated From XML?

I am populating the text of text fields with data from an XML file. I would like to do two things.
The code looks like this:

PHP Code:

DSGbox.textFirstName.htmlText = xmlDSG.name.first;    DSGbox.textLastName.htmlText = xmlDSG.name.last; 

First, I would like to format the text... bold, font size, etc...Second, I would like to concatenate the first and last name to appear on the same line without space in between caused by two text fields. I tried the following, but it didn't work.

PHP Code:

DSGbox.textFirstName.htmlText = xmlDSG.name.first + xmlDSG.name.last;
