Hi guys,
I have a doubt about testing
preceding-sibling processing-instruction.
I have this xml:
<root>
<child1>
child 1
</child1>
<?proc?>
<child2>
child 2
</child2>
</root>
And I need to know if child2 has the first
preceding-sibling as a processing-instruction. In this case it should
return true.
But it isn't true. There is a text node between
the processing instruction and <child2>.
The xml can come like this too:
<root>
<child1>
child 1
</child1>
<child2>
child 2
</child2>
</root>
In this case it should return false
and like this:
<root>
<?proc?>
<child1>
child 1
</child1>
<child2>
child 2
</child2>
</root>
and here false too.
I tryed something like this
preceding-sibling::*[1]/name()|preceding-sibling()[1]/name = 'proc'
but it didn´t work.
Can anyone help me??
The following:
preceding-sibling::node()[not(self::text())][1]/
self::processing-instruction('proc')
says:
"Get the preceding sibling nodes of any kind, looking only at the
non-text nodes, then looking only at the first of those, checking
that node is a processing instruction with the name 'proc'."
I hope this helps.
