    static NodeSet
    nodeSet(ExpressionContext myProcessor, Object rtf)
    The exsl:node-set function converts a result tree fragment (which is what you get when you use the content of xsl:variable rather than its select attribute to give a variable value) into a node set.
    static String
    The exsl:object-type function returns a string giving the type of the object passed as the argument.

      public static String objectType(Object obj)
      The exsl:object-type function returns a string giving the type of the object passed as the argument. The possible object types are: 'string', 'number', 'boolean', 'node-set', 'RTF', or 'external'. Most XSLT object types can be coerced to each other without error. However, there are certain coercions that raise errors, most importantly treating anything other than a node set as a node set. Authors of utilities such as named templates or user-defined extension functions may wish to give some flexibility in the parameter and argument values that are accepted by the utility; the exsl:object-type function enables them to do so. The Xalan extensions MethodResolver converts 'object-type' to 'objectType'.
      Parameters:
      obj - The object to be typed.
      Returns:
      objectType 'string', 'number', 'boolean', 'node-set', 'RTF', or 'external'.

    • nodeSet

      public static NodeSet nodeSet(ExpressionContext myProcessor, Object rtf)
      The exsl:node-set function converts a result tree fragment (which is what you get when you use the content of xsl:variable rather than its select attribute to give a variable value) into a node set. This enables you to process the XML that you create within a variable, and therefore do multi-step processing. You can also use this function to turn a string into a text node, which is helpful if you want to pass a string to a function that only accepts a node set. The Xalan extensions MethodResolver converts 'node-set' to 'nodeSet'.
      Parameters:
      myProcessor - is passed in by the Xalan extension processor
      rtf - The result tree fragment to be converted to a node-set.
      Returns:
      node-set with the contents of the result tree fragment. Note: Already implemented in the xalan namespace as nodeset.
