Given the following XML snippet
<opa id=“opa">
<Foo name="SubFoo Level One" id="Foo">
<Foo name="SubFoo Level Two" id="Foo_2">
<bar id="Bar" name="A Bar">
<bar name="Bar Level Three" id="Bar_2">
<Foo id="oma">OmaFoo</Foo>
</bar>
</bar>
<Foo name="Fuzz Level Four" id="Fuzz"/>
</Foo>
<Foo name="SubFoo Level Two" id="Foo_3">
<fuzz name="Fuzz" id="Fuzz_2"/>
</Foo>
</Foo>
</opa>
How would I go about to find the depth of an item found with an LPATH? E.g.
//[id="Foo_3"] would find a node at depth 2 (assuming <opa> is at level 0)
while //[id=“Fuzz_2"] would find a node at depth 3 and in either cases I would
like to get that number (2 or 3) as well as the actual node. I can assume the
values for ‘id’ are unique.
I was wondering how I could go about finding the ‘depth’ of an item in the XML
when using the LMTX built-in functions to work with XML. I don’t think there is
a default function for that, is there?
