Help required in changing the contents of a string

Question

hi guys
I'm reading in a series of xml files which contain a passage
of text like that below
Here is an example:
Since iritis is associated with HLA B27, it may obviously
occur in any of the <GLOSS
ID="seronegative">seronegative</GLOSS><SMALLIMAGE
width="348" height="254">charcothip.jpg</SMALLIMAGE>
I am displaying this text in a html textfield. However for it
to display properly, I need to replace the <SMALLIMAGE> tag
with
<IMG SRC="charcothip.jpg"/> etc
I can do a replace on <SMALLIMAGE and turn it to <IMG ,
however how do i add the SRC="charcothip.jpg"> ?
can anybody provide me with some suggestions for how to do
this?
Any ideas and suggestions would really be appreciated
Thanks

If you can replace <SMALLIMAGE with <IMG then I am not
sure why you couldn't include the SRC="charcothip.jpg" with the
<IMG portion?
How are you replacing it currently? Could you store the
replacement string in a variable and use it instead.
var replacementString:String = "<IMG
SRC=\"charcothip.jpg\"";
Then you could do something like this (assume the myStr holds
the XML String):
var myArr:Array = new Array();
myArr = myStr.split("<SMALLIMAGE");
myStr = myArr.join(replacementString);
Obviously, this will only work if you are replacing all of
the <SMALLIMAGE pieces with the same image. If not then you
could use the following:
var searchFor:String = "<SMALLIMAGE";
var newString:String = myStr.substring(0,
myStr.indexOf(searchFor));
newString += replacementString;
newString +=
myStr.substr(myStr.indexOf(searchFor)+searchFor.length);
You can keep the width and height attributes since Flash will
recognize those when rendering the HTML.
