Subject: [xsl] Using the value of an element in a test condition From: "Roger L. Costello" <costello@xxxxxxxxx> Date: Thu, 07 Feb 2002 12:15:38 -0500 |
Hi Folks, I have an XML document that contains conditions which must be tested in another XML document. For example, here's document 1: <root> <condition>not(A and B)</condition> <condition>A = 'hello'</condition> </root> Here's document 2: <root> <A>hello</hello> </root> I need to test document 2 against each condition (which is data) in document 1. Suppose that I create a variable, cond, whose value is the first condition listed above: cond |--------------| | | | not(A and B) | | | |--------------| Suppose that my current context is document 2. I cannot simply do this: <xsl:if test="$cond"> Document 2 meets this condition: <xsl:value-of select="$cond"/> </xsl:if> The xsl processor will simply test to see if the cond variable has a value. That's not what I want. I want the xsl processor to evaluate the value of cond. So, I want something like this: <xsl:if test="evaluate($cond)"> Document 2 meets this condition: <xsl:value-of select="$cond"/> </xsl:if> Of course I made up this evaluate() function. Is there something equivalent in xslt/xpath? In other words, how do I solve this problem? /Roger XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
