Subject: RE: [xsl] Can grouping here the solution ? From: Emma Burrows <Emma.Burrows@xxxxxxxxxxx> Date: Tue, 22 Nov 2011 16:08:05 +0000 |
I find it helpful to consider that from XSLT's point of view, everything in an XML document is a node. :) If you have: <page>page <!-- was 2 now changed-->1</page> Then the content of <page> is the following sequence: 1. text()[1] = "page " 2. comment() = "was 2 now changed" 3. text()[2] = "1" page/text() is therefore a set of text()[1] and text()[2] -----Original Message----- From: Echlin, Robert [mailto:Robert.Echlin@xxxxxxxxxxxxx] Sent: 22 November 2011 15:53 To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Cc: Robby Pelssers Subject: RE: [xsl] Can grouping here the solution ? Wow. I would have thought that "text()" would return the text, not a sequence of nodes. That's really counter intuitive.

If the input has any comments for example: <page>page <!-- was 2 now changed-->1</page> page has string value "page 1" so will work as expected if selected with an xpath of page but page/text() selects a sequence of two text nodes with values "page " and "1" which will either do the wrong thing, or generate an error, depending on how its used.
