Subject: Re: [xsl] Typing Variable as AnyURI - Problem From: Michael Kay <mike@xxxxxxxxxxxx> Date: Thu, 13 Sep 2012 08:31:48 +0100 |
<xsl:variable name="VMScall" as="xs:anyURI"> <xsl:value-of> <xsl:apply-templates select="..."/> </xsl:value-of> </xsl:variable>

This stylesheet is supposed to construct an HTTP call.
If I type the variable VMSCall as anyURI I get
net.sf.saxon.trans.XPathException: A sequence of more than one item is not allowed as the value of variable $VMScall
With the casting in the call to the document function (and an untyped variable) it works however if the variable is typed (despite casting to anyURI) it still yields the above error.
If the call to the document function is cast as xs:string I get net.sf.saxon.trans.XPathException: Exception thrown by URIResolver
My expectation is that if I type the variable as anyURI it should work without the need to cast the document call. AAMOF I also expected the call to work without having to type the variable or cast the document function call.
