While coding the XSLT stylesheet for IE, you cannot write logic that depends on whitespace text nodes. Because, as Mike explained, with IE, whitespace text nodes are stripped from source XML before the XML tree is handed to the XSLT engine. This behaviour is observed only when we use XSLT in IE using xml-stylesheet PI.
Hi
I'm working on a project involving an XML import into the FileMaker DB package. I'm using Internet Explorer to do quickie proofing on my stylesheets before using them in FM since FM is a bit of a kludge.
I got one bit working the way I wanted in IE, but got a different result when I moved it into FM.
Using the IE STYLESHEET and XML INPUT 1 below, I got IE RESULTS FROM BOTH INPUTS vs FM RESULTS FROM INPUT 1. The "normalize-space(text())" picked up the B2 text in IE but didn't in FM.
I ran about a dozen different versions of the XML input, removing 1 or more line breaks from different places. IE always picked up the B2 text; sometimes FM did, sometimes it didn't (see at FM RESULTS FROM INPUT 2 for one where FM did work).
Empirically, if <BBB><CCC> were on the same line, IE & FM returned the same results; if <BBB><CCC> were on separate lines, the results were different.
I'm working on a PC running XP SP2, IE 6 SP2 and FM 8.03. FM says they're using an Xerces-based XML parser and an Xalan-based XSLT processor (Xerces-C 1.6.0, Xalan-C 1.3.0). My stylesheets use the same XSLT, but for FM I have to remove the HTML and add a bunch of required metadata. It's longish so I didn't include it but I can if someone needs to see it. The line breaks are the standard Windows hex 0D 0A pair.
Does anybody have any suggestions as to what is going on? - Is the placement of the B2 text valid XML? - Is this a difference between IE & Xalan? - What results should I expect - B2 or not B2? (Gee, I should have used 2B as the sample!)
Thanks in advance
