Avoid namespace verification in xpath processing

Recently I dealt with a lot of xpath expressions, when implementing and it becomes cumbersome sometime to concern on namespaces when it’s not that much essential. We can use Regular expressions to bypass the namespace verfication on xpath.

eg -

<bpel:from part="payload" variable="profileProcessorInput">
    <bpel:query queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">
        <![CDATA[tns:profiles/ns1:Profile[round($itemIterator)]/ns1:club_code]]>
    </bpel:query>
</bpel:from>

Can be replaced by

<bpel:from part="payload" variable="profileProcessorInput">
    <bpel:query queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0">
        <![CDATA[tns:profiles/*[local-name() = 'Profile'][round($itemIterator)]/*[local-name() = 'club_code']]]>
    </bpel:query>
</bpel:from>
