From a file with these contents
<beansProjectDescription>
<configs>
<config>src/main/webapp/WEB-INF/applicationContext1.xml</config>
<config>src/main/webapp/WEB-INF/applicationContext2.xml</config>
</configs>
</beansProjectDescription>
I want to extract a string with this content
"src/main/webapp/WEB-INF/applicationContext1.xml,src/main/webapp/WEB-INF/applicationContext".xml"
Right now I'm using this code
<x:parse var="beansProject" xml="${f}" />
<x:set var="configs" trim="true"
select="$beansProject/beansProjectDescription/configs/config"/>
<j:forEach var="infile" indexVar="i" items="${configs}">
<j:if test="${i gt 0}">
<j:set var="inputs" value="${inputs},"/>
</j:if>
<j:set var="inputs" value="${inputs}${infile.text}"/>
</j:forEach>
But for my taste this is much too pedestrian.
