Hi Aslam,

this is more an xpath expression then a slide question I guess, but your XPATH will need be this:

<instruction property="answer" xpath="/Q/question/ques/@answer" />
<instruction property="output" xpath="/Q/question/ques/@output" />

I have to remind you though that this will not extract multiple occurences of the question xpath, since the values are stored within an attribute of the node, so you will get the first result only inside you extracted property. Which is in this case 'india' and 'screen'.

According to the documentation inside the source code it should work on text nodes.

http://svn.apache.org/repos/asf/jakarta/slide/trunk/src/share/org/apache/slide/extractor/SimpleXmlExtractor.java

Another solution is that you could use a different extractor or a custom one. For Hippo Repository [1] (a content repository based on Slide) we created several new extractors. There is multivalueXMLProperty extractor which you could use in this case. It extracts all values comma seperated into a single value.

Kind regards,

Jeroen Reijn
