Executing for all elements in an xml document...

	We have a nightly pull procedure that connects to a remote server
via https with basic authentication and performs a <get> to retrieve a one
file at a time. The owners of the remote server have set up the server so
that when I submit to the root directory an xml representation of the
directory is returned. 
	My challenge is to perform a series of tasks on each of the files
listed. Currently I have a list of the files hard-coded in a property that I
iterate through. I would like to iterate based on the elements in the xml
document. Is this possible?

Here is the modified result of the directory listing

<files>
	<file id="1">file1.DAT.zip</file>
	<file id="2">file2.DAT.zip</file>
</files>

Here is the hard coded property file that I use:

agenciesList= file1.DAT.zip, file2.DAT.zip

Why not use a XSLTransformation to retrieve the necessary information in a 
more Ant-friendly format?

Attached is an xpath iterator (compile with java SE 5.0) that can be used
with ant-contribs's for task as follows:

<project default="compile" xmlns:ac="antlib:net.sf.antcontrib">
  <target name="compile">
    <mkdir dir="classes"/>
    <javac srcdir="src" destdir="classes"/>
  </target>
  <target name="test" depends="compile">
    <typedef name="xpathiter" classname="XPathIterator"
             classpath="classes"/>

    <ac:for param="item">
      <xpathiter expression="/files/file/text()"
                 file="files.xml" trim="true"/>
      <sequential>
        <echo>Widget is @{item}</echo>
      </sequential>
    </ac:for>

  </target>
</project>

RE: Executing for all elements in an xml document...

I use a similar XML file in one of my Ant files. I use a reg exp to extract
the relevant info from each <file> line. I put the relevant info into a
semi-colon delimited property then use that later in the Ant file for
further processing.

Here is the target I use for reading the XML file, selecting the
translatable files from the list, and making the projXLFileList property.
<target name="loadprojxlfilelist" depends="init">
  <loadfile property="projXLFileList" srcFile="${PROJECTFILE}">
    <filterchain>
      <tokenfilter delimOutput=";">
        <ignoreblank/>
        <containsregex
pattern=".*&lt;file.*type=&quot;([^&quot;]*)&quot;.*translate=&quot;XL&quot;
.*inputname=&quot;([^&quot;]*)&quot;.*outputname=&quot;([^&quot;]*)&quot;.*"
flags="is" replace="/type &quot;\1&quot; /inputname &quot;\2&quot;
/outputname &quot;\3&quot;"/>
      </tokenfilter>
    </filterchain>
  </loadfile>
</target> 
You should be able to modify the reg exp to do what you want in your
particular file. You can also change the delimiter to a comma if you want.

Have a look at xmltask. This can execute ant targets for nodes in a given
xml file. Which looks like exactly what you need.

Re: Executing for all elements in an xml document...

Posted by Matt Benson <gu...@yahoo.com>.
For each file listed in the XML structure you want to
perform a series of operations:  store the remote file
locally using <get>, then do some arbitrary
processing, correct?  Without knowing much about XSLT,
you might use that or some home-brewed means (custom
Task) of converting the XML to a list like you are
already using.  You might experiment with making the
conversion using regular expressions, perhaps with
AC's <propertyregexp>.  It might take a true regexp
guru, but I think it may be possible.
