No particular thoughts spring to mind. Can you forward me a minimal copy
of the build.xml and log4j.xml that exhibits the problem so I can run
here and look at what's happening ?
You should be able to do the copy/attr step in one <xmltask> invocation,
using a buffer, btw (you can't do it using properties for reasons you'll
have discovered already).
Once I get a copy of the files I can investigate further. Which Ant/JDK
are you using, btw ?

I'm trying to run 'ant build build' where build is a target that

[xmltask] Indenting resultant document
The file that is being parse is a static file and is not modified by
the task -- rather the source file is used to create the target file
like so:
<taskdef name="xmltask"
classname="com.oopsconsultancy.xmltask.ant.XmlTask"
classpathref="master-classpath"/>
<xmltask source="${src.dir}/log4j.xml">
<xmlcatalog refid="dtds"/>
<copy
path="log4j:configuration/[EMAIL PROTECTED]'file']/[EMAIL PROTECTED]'File']/@value"
attrValue="true" property="log.path.relative"/>
</xmltask>
<xmltask source="${src.dir}/log4j.xml" dest="${build.dir}/log4j.xml"
system="log4j.dtd">
<xmlcatalog refid="dtds"/>
<attr
path="log4j:configuration/[EMAIL PROTECTED]'file']/[EMAIL PROTECTED]'File']"
attr="value" value="${basedir}/${log.path.relative}" />
</xmltask>
I cannot figure out why the second time it fails so I thought I'd ping
the list to see if anybody has a clue.
Thanks,
Rob
