Hi,
I was trying to add an XPath activity to a workflow that processes an
XML with an xlink:href attribute:
<?xml version="1.0" encoding="UTF-8"?>
<ns3:directoryContents xmlns:ns3="http://ns.taverna.org.uk/2010/xml/server/rest/";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:ns2="http://ns.taverna.org.uk/2010/xml/server/";>
<ns2:file
xlink:href="http://localhost:8080/taverna-server/rest/runs/6dcaa906-175c-4dc6-a4c5-38b7ddbda5fb/wd/out/out";
ns2:name="out">out/out</ns2:file>
</ns3:directoryContents>
The following XPath expression is generated for the attribute xlink:href:
/ns3:directoryContents/ns2:file/@xlink:href
This works in the XPath activity configuration window but the
HealthChecker complains that the "XPath activity - has missing namespace
mappings". When I remove the xlink namespace from the XML, everything
works fine.
I think this might be a bug in the method
hasMissingNamespaceMappings(XPathActivityConfigurationBeanconfigBean)in
XPathActivityHealthChecker.java. Here the part before ":" is used as
prefix including the "@"-sign.
As a workaround I currently use:
/ns3:directoryContents/ns2:file/@*[local-name()="href"]
Regards,
Markus
