Subject: RE: [xsl] XSLT 2.0 and implementation of fn:idref in Saxon 7.9 From: "Michael Kay" <mhk@xxxxxxxxx> Date: Sat, 13 Mar 2004 22:40:28 -0000 |
# # Did I misunterstand the meaning of the fn:idref (Finds the elements that # link to the element with a given ID value i.e. This function allows # reverse navigation from IDs to IDREFs.) ? Yes, you misunderstood it. The spec says: A node references an ID value if it is an element or attribute node whose type is xs:IDREF or xs:IDREFS. So if you have an attribute of type xs:IDREFS, then the idref() function will return that attribute, not the element containing it. The reason for this is that you can have several IDREF attributes on an element, e.g. <person id="id005" father="id001" mother="id002"/> You want to know not only that person id005 has a reference to id001, but which attribute contains this reference. You can always get the element node if you want, just use idref($x)/.. Michael Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
