Usage

omni_xml: XML toolkit

The omni_xml extension provides XML toolkit functionality using pugixml, useful when PostgreSQL is built without XML support or the xml2 extension.

XPath Querying

omni_xml.xpath(xml_text, xpath_query) – Returns a table with path and value columns.

Element queries:

SELECT * FROM omni_xml.xpath('<node>value</node>', '/node');
-- Returns the complete XML element

Text extraction:

SELECT * FROM omni_xml.xpath('<node>value</node>', '/node/text()');
-- Returns just the text content

Namespace handling:

SELECT * FROM omni_xml.xpath('<ns:node>value</ns:node>', '/ns:node');

Note: The underlying library is not fully W3C-conformant; the namespace:: axis is unsupported.
