nodeSet(ExpressionContext myProcessor, java.lang.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 java.lang.String

Method Detail

objectType
public static java.lang.String objectType(java.lang.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, java.lang.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 processorrtf
- 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.
