Allows surrounding white space

Parameters:

nodeString - Node string to parse

parseNode

public static Node parseNode(java.lang.String nodeString,
                             PrefixMap pmap)

Parse a string into a node.

Allows surrounding white space.

Parameters:

nodeString - Node string to parse

pmap - Prefix Map, null to use no prefix mappings

Returns:

Parsed Node
