Match multiple attribute values in html for ant buildscript - html

Question

I want to match mulitple values of a attribute for replacing. for example
<div class="div h1 full-width"></div>
Should produces div, h1 and full-width as seperate matches.
I want to do this to prefix the classes. So instead of div h1 full-width it should be pre-div pre-h1 pre-full-width
The regex I have sofar is
(?<=class=["'])(\b-?[_a-zA-Z]+[_a-zA-Z0-9-]*\b)+
This matches only the first class. This is offcourse because that is the only thing this pattern should match :( I tried to make the lookbehind take more then just class=" but I just end up with it taking everying and leaving nothing to replace.
I want to make a pattern that matches any value individually between the quotes of the class attribute.
I want to do this for an Ant buildscript that processes all files and replaces the class="value1 value2 value3" with a set prefix. Ive done this with little trouble for replacing the classes in css files but ye html seems to be alot trickier.
It is a Ant buildscript. Java regexp package is used to process the pattern. The ant tag used is: replaceregexp
The ant implemtentation of above pattern is:
<target name="prefix-class" depends="">
<replaceregexp flags="g">
<regexp pattern="(?<=class=['"])(\b-?[_a-zA-Z]+[_a-zA-Z0-9-]*\b)+"/>
<substitution expression=".${prefix}\1"/>
<fileset dir="${dest}"/>
</replaceregexp>
</target>

Answer 1

I don't think that you can find n (or in your case 3) different class entries and substitude them in one simple regexp. If you need to do this in ant i think you have to write your own ant task. A better way would be xslt, are you familiar with xslt?

Gave up on Ants ReplaceRegExp and sorted my problem with XSLT to transform xhtml to xhtml.
Following code adds a prefix to all values of a elements class attribute. the xhtml source document must be properly formatted to be parsed.
