Re: [xsl] Testing if first child is text or an element?

["dvint dvint@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

I pulled it out as a named template because I needed to test the general
conditions in many places. Performance currently isn't an issue. After this
conversion effort this code will not have a use.I may have more of these mixed
content situations to handle and will keep this in mind for a possible
restructure.B Sent from my Verizon, Samsung Galaxy smartphone

Testing if first child is text or an element?

Hi,
B 
Instead of a conditional on the container, how about handling only the node we
want to amend?
B 
<xsl:template match=binfo/child::text()[1][matches(.,b\Sb)]b>
B B  <xsl:text>+</xsl:text>
B B <xsl:next-match/>
</xsl:template>
B 
Much simpler, I think, probably also performs better.
B 
Apologies if I misconstrue the question!
B 
Cheers, Wendell

That did the trick. Figured I needed a normalize-space in there somewhere,
just not sure how to add it.

child::* selects element nodesB  only I think.

But do realize that the second info element also starts with a pure
whitespace text node child.


So, unless you strip-space, both your case have a text node child as the
first child, you might want to check

B B  info[node()[1][normalize-space()] instance of text()]]

or

B B  info[node()[1][normalize-space()][self::text()]]

to match the info element that starts with a text node that has more
than whitespace.
