Oxygen XML Forum

Hello,

In Oxygen 25 and 26 we encountered a strange behavior when evaluating an xpath expression with the XPath/XQuery builder.
We want to select all attributes in the entire document except the first attribute of each element with this expression:
The result is confusing. It selects the first attributes except for the image element in line 13 (blue arrow).
I have tested the expression at https://www.videlibri.de/cgi-bin/xidelcgi with the same input file.
It gives the expected result there: Could this be a bug? Or can you explain the result the XPath builder in Oxygen returns here?

Thanks in advance and regards
Jörn

Hello Jörn,

Please consider using the XPath 3.1 SA engine from the drop-down menu instead of XPath 3.1.
The results should be as expected.

Hello,

It seems that the position() function take into account also the default attributes from the schema, even they are not in the document. For example in the "concept" element you have the 4 attributes: class, ditaarch:DITAArchVersion, domains, and id. You can use the following XPath expression "//concept/@*/name()" to get the list of attributes for the "concept" element.
Therefore, in your example the id attribute is on position 4, and this is why is returned by the XPath expression. When "XPath 3.1 SA engine" is used, the default attributes are returned as last attributes in the list.
