Subject: Re: [xsl] iterating a nodeset (provided by XML or XSL) in a custom template (image-chooser) From: David Carlisle <davidc@xxxxxxxxx> Date: Wed, 9 Apr 2003 11:12:50 +0100 |

No the instructions in teh template will have been applied, but without seeing the template it's hard to say why you did not get what you expected. - in general, how can I _build_ a nodeset in an XSL template and pass it as a parameter xsl:call-template? (and what's the best way to process that nodeset?) If you are actually constructing nodes then you can not do this in XSLT 1 without a node-set extension function to convert the result tree fragment back to a node set, but I do not think you are doing that here, you are not building new nodes, just getting them from the source or the stylesheet. Actually it's probably a bit easier to have your other image documents not directly in your xsl file but in a sibling xml file that you bring in via document() > I'm not sure how work through a list of images. if you have some <img/> elements in the main source file and some in a file say defautimage.xml then you can just <xsl:apply-templates select="/some/path/to/img | document('defautimage.xml')/some/other/path/to/img"/> will apply templates to images in your input document and your defautimage.xml file. However you have to decide what the Xpaths need to be based on teh structure of your input.
