Body
Here's a fragment of my own solution. I won't mark it as accepted, because it doesn't solve the general text-parse problem (like php's preg_match_all). But maybe someone find it interesting. It is a little bit messy - I use ant properties and flaka EL variables, but it illustrates how to use them together. Here's the code: <pre><code>filename: process.xml </code></pre> <pre><code> <taskdef uri="antlib:it.haefelinger.flaka" resource="it/haefelinger/flaka/antlib.xml" classpath="ut/ant-flaka.jar" /> <taskdef uri="antlib:net.sf.antcontrib" resource="net/sf/antcontrib/antlib.xml" classpath="ut/ant-contrib-1.0b3.jar" />  <target name="correct-xmls"> <fl:install-property-handler /> <property name="slashn" value="${line.separator}" />  <fileset dir="${fname}" includes="**/*.xml" id="xml-classes"> <contains text="&lt;resprops&gt;" /> </fileset> <fl:for var="xn" in="split('${toString:xml-classes}', ';')"> <fl:let>curfile = file(concat('${fname}','/',xn))</fl:let> <fl:let>tgtfile = file(concat('${fname}','/',xn,'.new'))</fl:let> <fl:echo>#{ format('file %s, last modified %tD, size: %d', curfile.path, curfile.mtime, curfile.isdir ? 0 : curfile.size) }</fl:echo> <fl:unset>xmlfile.contents</fl:unset> <loadfile property="xmlfile.contents" srcFile="#{curfile}" /> <fl:let>outstr = ''</fl:let> <fl:for var="str" in="split('${xmlfile.contents}', '\n')"> <fl:unset> xval </fl:unset> <ac:propertyregex property="xval" input="#{str}" regexp="pos-x\s*=\s*&quot;([0-9\-]+)&quot;" select="\1" override="true" />  <fl:let>resstr ::= str</fl:let>  <fl:when test="not empty '#{property.xval}'"> <fl:let>outval = (property.xval * 15.5 + 0.5) </fl:let>  <ac:propertyregex property="gotv" input="#{outval}" regexp="([0-9\-]+)\." select="\1" override="true" /> <ac:propertyregex property="resstr" input="${resstr}" regexp="pos-x\s*=\s*&quot;([0-9\-]+)&quot;" replace="pos-x = &quot;#{gotv}&quot;" override="true" /> </fl:when>  <fl:let> outstr = format('%s%s%s', outstr , resstr, slashn) </fl:let> </fl:for>  <echo file="#{tgtfile}" encoding="utf-8">#{outstr}</echo> </fl:for> </target> </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
