Example: Index all XML tags

You can use the all_xmltags parameter to index all of the tags in a column.

Given the XML fragment: 
<book>
	<title>Graph Theory</title>
	<author>Stewart</author>
	<date edition="second">January 14, 2006</date>
</book>
To create an index for all the XML tags, use the SQL statement: 
CREATE INDEX book_bts ON books(xml_data bts_lvarchar_ops) 
USING bts(all_xmltags="yes") IN bts_sbspace;
The index will contain three fields that can be searched: 
title:graph theory
author:stewart
date:january 14, 2006

The top level <book></book> tags are not indexed because they do not contain text values. The edition attribute is also not indexed.

If you enable path processing with the xmlpath_processing parameter, you can index the full paths: 
CREATE INDEX book_bts ON books(xml_data bts_lvarchar_ops) 
USING bts(all_xmltags="yes",xmlpath_processing=”yes”) IN bts_sbspace;
The index will contain three fields with full paths that can be searched: 
/book/title:graph theory
/book/author:stewart
/book/date:january 14, 2006
