Subject: appending to fileset
/*
Is there a way to incrementally add files to a fileset? I am building a
fileset by looping through an XML file and need to add files to a named
fileset one by one if they meet certain criteria. Is this possible
without converting everything into paths or strings or stuff like that?
*/
quick shot, untested, seems a bit long winded
maybe there's a better/shorter solution ?!
don't know your xml, so i took an example structure =
...
<file>
<file.1>
<name>...</name>
</file.1>
<file.2>
<name>...</name>
</file.2>
...
<!-- Import AntContrib -->
<taskdef resource="net/sf/antcontrib/antlib.xml" />
<!-- Import XMLTask -->
<taskdef name="xmltask"
classname="com.oopsconsultancy.xmltask.ant.XmlTask"/>
<target name="...">
<patternset id="basic_files" includes="*.txt **/*.properties"/>
<fileset dir="Y:/test" id="namedfileset">
<patternset refid="basic_files"/>
</fileset>
<var name="filelist" value=""/>
<xmltask source="your.xml">
<call path="//file/*">
<param path="name/text()" name="fname" />
<actions>
<if>
<your condition(s) goes here ... />
<then>
<var name="filelist_tmp" value="${filelist}"/>
<var name="filelist" unset="true"/>
<var name="filelist" value="${filelist_tmp} @{fname}"/>
</then>
</if>
</actions>
</call>
</xmltask>
<patternset id="ext_files" includes="${filelist}"/>
<fileset dir="Y:/test" id="ext_namedfileset">
<patternset refid="ext_files"/>
<patternset refid="basic_files"/>
</fileset>
</target>
notes =
when using patternset you are more flexible
with the appropriate xpath expression and your condition(s) between
<actions> <if> ... </if> ...</actions> you take control what is matched
and
whether the matched gets included in the space separated patternset
(don't know whether the blank at the end of ${filelist} is a problem !?)
Beside that you can put other tasks into the <actions .../> scope if
needed
then later construct a fileset with the same dir as your first fileset
and include
both patternsets via refid= ... and finally you have your extended
fileset.
