Implements an interface to the XPATH Document. XML contained in a file or binary stream may be selected and navigated. %XML.XPATH.Document should never be created directly with %New(), but via the CreateFromFile() or CreateFromStream() factory methods
This holds a string specifying prefix mappings for the document. This is a comma delimited list of prefix to namespace mappings. Each mapping is defined as a prefix, a space and then the uri to which that prefix maps. This is especially useful if the document defines a default namespace with the xmlns="http://somenamespaceuri" syntax but does not supply an explicit prefix mapping. For example, this PrefixMappings string would map the myprefix prefix to the http://somenamespaceuri uri. "myprefix http://somenamespaceuri
This holds the default ResultHandler
Use this method a create an instance of an %XML.XPATH.Document from a file path name.
Use this method to create an instance of an %XML.XPATH.Document from a binary stream. It's important to use a binary stream because if a character stream is used then (for a unicode cache) the characters will be automatically converted to unicode (utf-16). This can cause a problem if the XML stream has a header declaring a different coding as it introduces an inconsistency between the declared encoding and the actual encoding. This will cause the XML Parser to issue an error message and fail.
Use this method to create an instance of a %XML.XPATH.Document from a string.
The input string is expected to be UTF-8 encoded.
This method evaluates an XPATH context and expression. The context selects the intial nodeset from the document and the expression further filters the node set. See http://www.w3.org/TR/xpath for full details of XPATH syntax and usage If the method succeeds it returns a list of Results which can be queried for their types and values.
Evaluates an XPATH expression which returns a DOM Result
Evaluates an XPATH expression which returns a VALUE Result
Evaluates an XPATH expression which returns a VALUE Result ( demonstrates use of CreateFromString() )
May be called to determine the prefix defined for a particular url in the Prefix Mappings passed to the CreateFromXXX() calls
This is the setter for the PrefixMappings, it parses the mappings into an array which can be queried by the GetPrefix() method
