Subject Re: Multiple files to <java> task
Date Sat, 20 Jan 2007 07:42:56 GMT
well got 80% of the way there :)

The below will make a list of the filename surrounded by quotes.
(havn't tried it as part of a line= constrct yet.

<fileset dir="${src.home}" id="xmlcode.files">
      <include name="*.xml"/>

<pathconvert targetos="unix"
              pathsep="&quot; &quot;"
     <map from="${src.home}" to=""/>

<echo message="&quot;${xmlfiles}&quot;${line.separator}" />

However I noticed a buggaboo - the <map from="xx" to="xx" />  only 
does simple string substitution so unless you specify 
${path.separator} for every instance of it in all paths everywhere 
the mapping will not work right so my common practice of specifying 
all patht as unix paths when software recognizes them (ie: fileset 
does!) will not work.  Now I need to find the string substitutor so I 
can translate all the '/' to $path.separator} before the map operation

(xml is really the wrong thing to make a scripting system out of!)
