Thanks for the suggestion; I will take a look at the scriptselector you
mention. In the meantime I came up with a solution that uses just existing
ant and ant-contrib constructs. Here it is in case others are interested:
<!--
Purpose: confirm that file path/xxx.java contains comment "@doc
/api/subpath/xxx.html".
-->
<checkApiPath
srcdir="${javasrc}"
regexp=".*(com.cleancode..*)\.java"
includes="**/*.java"
/>
<macrodef name="checkApiPath">
<attribute name="srcdir"/>
<attribute name="regexp"/>
<attribute name="includes" default="**"/>
<attribute name="excludes" default=""/>
<sequential>
<!-- collect all source files -->
<pathconvert property="apiList">
<path>
<fileset dir="@{srcdir}"
includes="@{includes}" excludes="@{excludes}">
<containsregexp expression="@doc\s+/api/" />
</fileset>
</path>
</pathconvert>
<for list="${apiList}" param="file" delimiter=";">
<sequential>
<!-- reshape file path to match API name -->
<propertyregex property="shortfile" input="@{file}"
regexp="@{regexp}" replace="\1.html"
override="true"/>
<!-- grab corresponding line from file contents -->
<loadfile srcfile="@{file}" property="apiList.text">
<filterchain>
<linecontainsregexp>
<regexp pattern="@doc\s+/api"/>
</linecontainsregexp>
</filterchain>
</loadfile>
<!-- isolate api path -->
<propertyregex
property="apiList.text" input="${apiList.text}"
regexp=".*/api/[^/]+/(.*\.html)" replace="\1"
override="true"/>
<!-- validate -->
<if>
<not>
<equals trim="true"
arg1="${shortfile}" arg2="${apiList.text}" />
</not>
<then>
<echo level="warning"
message="${shortfile}: wrong api spec:
${apiList.text}" />
</then>
</if>
<!-- vital step: make property mutable (NB: nonstandard ant) -->
<var name="apiList" unset="true"/>
<var name="apiList.text" unset="true"/>
<var name="shortfile" unset="true"/>
</sequential>
</for>
</sequential>
</macrodef>

I dont know built in selector.
But you can write your own - e.g. using <scriptselector> and reuse of the
<containsselector>.
The filename and the fileobject are passed.
<project>
<pathconvert property="selected" pathsep="${line.separator}">
<fileset dir=".">
<!-- Checks if the content of the file contains the filename. -->
<scriptselector language="javascript" setbeans="true">
importClass(Packages.org.apache.tools.ant.types.selectors.ContainsSelector);
filenameWithoutSuffix = filename.substring(0,
filename.lastIndexOf("."));
cSel = new ContainsSelector();
cSel.setText(filenameWithoutSuffix);
self.setSelected( cSel.isSelected(basedir, filename, file) );
</scriptselector>
</fileset>
</pathconvert>
<echo>Selected files</echo>
<echo>${selected}</echo>
</project>

Betreff: Re: AW: AW: generate file list with parameterized regexp
My humblest apologies--I did not state my problem clearly. I
want to find a
set of files whose contents (not the file name) includes a
string based on
the name of the file containing it. That is, for each file
path/xxx.yyy, I
want to know if the file contains a string like this:
"See doc page at path/xxx.html".
So <containsregexp> seemed the most promising, as discussed,
but it uses
only a "constant" regexp, not a parameterized regexp.
