fm:remove

Use fm:remove to remove XML nodes (elements, text, other) from a DOM using XPath.

This is simple but dangerous as entire legs of data can be obliterated in one foul swoop.

SYNTAX

EXAMPLES

1. Remove a whole leg

<fm:remove match="/*/PON15B"/>

2. Remove specific elements under the root node

<fm:remove match="/*/FAC_NAME | /*/FAC_TYPE | /*/FIELD_NAME"/>

3. Remove all chemicals where SELECT_FLAG is true [relative XPath]

<fm:remove match="./CHEMICAL_LIST/CHEMICAL[SELECT_FLAG='true']"/>
