OSB Validate XQuery Xpath
A function that i find missing is to get the Xpath expression of a node. For example, suppose i only know the node name <theNode>, i'd like to get its complete path /Where/is/theNode.
Using this rather simple Xquery you can easily get the path to your node.
| declare namespace orcl = "http://www.oracle.com/weblogic_soa_and_more";
declare function orcl:findXpath($path as element()*)
as xs:string
{ if(local-name($path/..)='')
then local-name($path)
else concat(orcl:findXpath($path/..),'/',local-name($path)) };
declare function orcl:PathFinder($inputRecord as element(), $path as element())
as element(*)
{ |
With a path
<myNode>nodeName</myNode>
and a message
<node1><node2><nodeName>test</nodeName></node2></node1>
the result will be
node1/node2/nodeName
This is particularly useful when you use the Validate action of OSB because Validate only returns the xml node which is in error and not the full location itself. The following OSB project reuses this Xquery to reformat the result of the Validate Action.
Just send an invalid xml like
<myElem http://blogs.oracle.com/weblogic_soa_and_more">http://blogs.oracle.com/weblogic_soa_and_more">
<mySubElem>
</mySubElem>
</myElem>
you'll get as nice

Download the OSB project : sbconfig_xpath.jar
Enjoy.
