Just checked out the Slide CVS head to check it and it still works fine for me
:-)
Just took the demo configuration in Domain.xml:
<!-- Extractor configuration -->
<extractors>
<extractor classname="org.apache.slide.extractor.SimpleXmlExtractor"
uri="/files/articles/test.xml">
<configuration>
<instruction property="title" xpath="/article/title/text()" />
<instruction property="summary" xpath="/article/summary/text()"
/>
</configuration>
</extractor>
</extractors>
and put a file under /files/articles/ with name test.xml and content:
<article>
<title>Some title</title>
<summary>Summary</summary>
</article>
Everything worked fine!
Check that your event configuration contains the PropertyExtractorTrigger:
<!-- Event configuration -->
<events>
...
<listener
classname="org.apache.slide.extractor.PropertyExtractorTrigger" />
...
</events>
Check out if this works for your as well.
Cheers,
Daniel
