MINIMIZING THE COPYING OF AN EXTENSIBLE MARKUP LANGUAGE (XML) TREE WHEN REFERENCING TREE NODES DURING EXTENSIBLE STYLESHEET LANGUAGE TRANSFORMATIONS (XSLT) PROCESSING
The invention includes a label tree action and a generate reference action function. The label tree action can execute a first time a copy of an XML tree is made (or when an XML tree is analyzed and determined not to contain id_attributes). The add id_attribute can add an id_attribute for each element of the XML tree that does not already have an associated id_attribute. This attribute can be set to a value returned by an XSLT generate-id( ) function. The generate reference action can deliver a string that will be used to refer to a given element. When an id_attribute for the given element is present within the XML tree, the generate reference action can return a value of the id_attribute. When no id_attribute is present for the given element, the generate reference action can return a value of the XSLT generate-id( ) function for the element.
