Subject: [xsl] What's evaluated first: @select or xsl:with-param? From: "Vladimir Nesterovsky" <vladimir@xxxxxxxxxxxxxxxxxxxx> Date: Mon, 18 Oct 2010 08:19:41 -0700 |
Hello! I've seen a code like this: ---------- <xsl:variable name="a" as="element()?" select="..."/> <xsl:variable name="b" as="element()?" select="..."/> <xsl:apply-templates select="$a"> <xsl:with-param name="b" tunnel="yes" as="element()" select="$b"/> </xsl:apply-templates> ---------- It fails with an error: "An empty sequence is not allowed as the value of parameter $b". What is interesting is that the value of $a is an empty sequence, so the code could potentially work, provided processor evaluated $a first, and decided not to evaluate xsl:with-param. Whether the order of evaluation of @select and xsl:with-param is specified by the standard or it's an implementation defined?
