Fix XML extraction using XPath in DB2 #6285

Closed obruchez closed 5 months ago

obruchez commented 5 months ago

Following #1069, fix the workaround that was added in Provider (see fixedPath method).

Strangely, XPath expressions starting with "/*/" don't work with XML data extracted using XMLTABLE. The current workaround consists of replacing "/*/" with "//", which works but is semantically incorrect.

"A slash character (/) at the beginning of a path expression means that the path is to begin at the root node of the tree that contains the context node. That root node must be a document node."

Does that mean that DB2 doesn't consider a fragment of an XML tree as a document?

Using XMLDOCUMENT to "tag" the XML fragment as a document seems to work.
