Re: [xsl] document() function - friendly error message when load fails

[Abel Braaksma <abel.online@xxxxxxxxx>]

Hi Ovidiu,

What a coincidence: for the past few days we happen to have being 
discussing this very thing (though, more generic, about URI escaping and 
wrong URI references), see More meaningful error for "Fatal error during 
transformation: null" on the Saxon list.

Alas, that is about XSLT 2. You use MSXML, thus limited to XSLT 1. And 
XSLT 1 does not provide such function (nor does XPath 1 for that matter).

You can use msxsl:script, I suppose. If it supports normal JavaScript of 
VBScript (I never used msxml), I reckon you can employ the 
XMLHttpRequest object to try to load the file. If it returns a 404 (or 
any 4xx error), it is not there and you can act accordingly. Note, 
however, that this requires two times requesting the file: 1x for the 
XHR, and 1x for XSLT document().

Cheers,
