RE: get immediat preceeding node, if it is a comment

2002-10-04 03:01:19

- how to get the immediat preceeding node, when you don't 
know what it will 
be (element, comments, and for extension PIs, text())

 preceding-sibling::node()[1]

- how can I filter comments from it

<xsl:if test="preceding-sibling::node()[1][self::comment()]">
  ....
</xsl:if>

Don't forget though that most likely the immediate preceding element
will be some presentational whitespace, so you will need to strip that
out using:

<xsl:strip-space elements="*"/>

or a more specific selection in place of * (unless of course, you are
using msxml which strips it all out regardless).

Subject: [xsl] get immediat preceeding node, if it is a comment


Hello,

I have a little problem, which I am unable to find the 
solution because I 
must think to devious...

I have a XML with some comments on the nodes, just before, 
that I want to get.

My problem is : there are not always there, so I cannot just use 
"preceding-sibling::comment()[1]".

Therefore, 2 questions :
- how to get the immediat preceeding node, when you don't 
know what it will 
be (element, comments, and for extension PIs, text())
- how can I filter comments from it

Thanks in advance.
