Method Detail

generateXPath

public static java.lang.String generateXPath(XmlCursor node,
                                             XmlCursor context,
                                             javax.xml.namespace.NamespaceContext nsctx)
                                      throws XPathGenerationException

Generates an XPath pointing to the position in the document indicated by node.

If the context parameter is null, the XPath is absolute, otherwise the XPath will be relative to the position indicated by context.

Note: the cursor position for the node parameter is not preserved

Parameters:

node - the position in the document that the generated path will point to

context - the context node; the generated path will be relative to it if not null and if pointing to an element on the path from the document root to node

nsctx - a namespace context that will be used to obtain prefixes; a (non-default) namespace mapping must be available for all required namespace URIs

Returns:

the generated path as a String

Throws:

XPathGenerationException - if the path could not be generated: the cursor is in a bad position (like over a comment) or no prefix mapping was found for one of the namespace URIs

main

public static void main(java.lang.String[] args)
                 throws XmlException

Throws:

XmlException
