APPLIES TO

SYMPTOMS

When you use the XPATH/XSL function-available function, you see that the function returns False for the XPATH/XSL element-available function, although the element-available function is implemented in Microsoft XML 3.0.

You expect function-available to return True for implemented XPATH/XSL functions.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This bug was corrected in Microsoft XML 3.0 Service Pack 1.

Steps to Reproduce Behavior

1. Create the XML document containing several XPATH/XSL function names, including element-available function. The XML document refers to an XSL stylesheet.
   1. Create a new text document by using Microsoft Notepad or another text editor.

   2. Paste the following code into the new text document:

      <?xml version="1.0"?>
       <?xml-stylesheet type="text/xsl" href="functions.xsl"?>
      <functions>
          <function>boolean</function>
          <function>ceiling</function>
          <function>concat</function>
          <function>contains</function>
          <function>count</function>
          <function>element-available</function>
          <function>floor</function>
          <function>function-available</function>
      </functions>
                              

   3. Save the text file as C:\Functions.XML.
2. Create the XSL stylesheet to process the XML document. The XSL stylesheet checks each function listed in the XML document to see if the function is available in XSL. The stylesheet uses the XSL function-available function to check each function name.
   1. Create a new text document by using Microsoft Notepad or another text editor.

   2. Paste the following code into the new text document:

      <?xml version="1.0"?>
      <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                      xmlns:msxsl="urn:schemas-microsoft-com:xslt"
                      version="1.0">
      <xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
      
      <xsl:template match="//function">
      <xsl:if test="function-available(.) = False">
           function-available is False for <xsl:value-of select="."/>  
      </xsl:if>
      </xsl:template>
      </xsl:stylesheet>
                              

   3. Save the text file as C:\Functions.XSL.
3. Open the XML document in Microsoft Internet Explorer (IE) to process the XML document using the XSL stylesheet. Note that the following output indicates that function-available function returned False:

   function-available is False for element-available
