Subject: RE: [xsl] Can grouping here the solution ? From: Robby Pelssers <Robby.Pelssers@xxxxxxx> Date: Mon, 21 Nov 2011 19:10:15 +0100 |
Ok Ken, thx for the advice. I actually never used to do so but at some point in time I figured it would express more clearly the intent. I guess I should just always assume this by default to safe on typing. -----Original Message----- From: G.

In all of my professional work with XSLT I have very rarely ever had to address text() nodes individually.

Consider if your user has the following: <datum>2003<!--OCR read this '3' as an '8'-->-05-02</datum> The expression "substring(datum,6,2)" evaluates as "05" as expected. The expression "substring(datum/text(),6,2)" triggers a runtime error because of supplying more than one node for the first argument. Remember in XPath that the value of an element is the concatenation of that element's descendent text nodes. I tell my students if they ever think they need to address a text node directly, to think again because they probably don't. I hope this is helpful. . . . . . . . . . .
