Aug 25, 2010 · You should start with the PostgreSQL XML Data Type and PostgreSQL XML Functions documentation in the manual when getting started with PostgreSQL's XML support. This page discusses the planning of that work, which is now largely complete, rendering the following obsolete.

Instead of returning the individual XML values that satisfy the XPath, this function returns a Boolean indicating whether the query was satisfied or not. This function is equivalent to the standard XMLEXISTS predicate, except that it also offers support for a namespace mapping argument. Syntax: xpath_exists(xpath, xml [, nsarray]) Example. Code:

8.13.3. Accessing XML Values. The xml data type is unusual in that it does not provide any comparison operators. This is because there is no well-defined and universally useful comparison algorithm for XML data. One consequence of this is that you cannot retrieve rows by comparing an xml column against a search value. XML values should therefore typically be accompanied by a separate key field ...

8.14. XML Document Support. XML (Extensible Markup Language) support is not one capability, but a variety of features supported by a database system. These capabilities include storage, import/export, validation, indexing, efficiency of modification, searching, transforming, and XML to SQL mapping. PostgreSQL supports some but not all of these XML capabilities.

9.14.1. Producing XML Content. A set of functions and function-like expressions are available for producing XML content from SQL data. As such, they are particularly suitable for formatting query results into XML documents for processing in client applications.
