在OSB项目中使用Xquery查找属性（使用Eclipse）

Question

This is an OSB project in Eclipse.

Somewhere along a long chain of OSB processes, I have the following piece of XML, stored in $xdata:

<RECORDS xmlns="url1" xmlns:xsi="url2" xmlns:schemaLocation="url3" ver="v7">
...
</RECORDS>

I want to find the value of the attribute ver . I created the following xquery in an OSB Assign node to get the attribute:

$xdata/occ:RECORDS/@ver

(I created a namespace, url3, called occ in the Namespaces part of the Assign dialog.) The purpose of the Assign is of course to capture the "ver" attribute.

Yet, it gets nothing, and it turns out not even the $xdata/occ:RECORDS works, it does not give the RECORDS node of the XML, it gives nothing. The only correct part is the $xdata, it gives the XML content, I checked the server log.

I suspect my problem is with namespaces as that's what I'm not too confident about.

The solution was pretty unexpected. When referring to an element in a variable other than $body, you apparantly have to omit the top parent node containing the element you need. In this case, you have to omit RECORDS. So the way to get the attribute is: $xdata/@ver
