Match multiple attribute values in html for ant buildscript

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 开发者_运维知识库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="(?&lt;=class=['&quot;])(\b-?[_a-zA-Z]+[_a-zA-Z0-9-]*\b)+"/>
    <substitution expression=".${prefix}\1"/>
    <fileset dir="${dest}"/>
   </replaceregexp>
</target>

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.
