I have the following situation.

PostgreSQL is  not configured with the option   --with-libxml

Having one text column where i am trying to run the following command
which is failing as expected its not configure with libxml. However, is
there any alternate way through which i can achieve this.

select xpath('///Name/text()', column1_xml::xml) from test;

Pull the text out and use another language to process:

https://en.wikipedia.org/wiki/XPath#Implementations

either externally or in a Postgres pl* function.


ERROR:  unsupported XML feature
DETAIL:  This functionality requires the server to be built with libxml
support.
HINT:  You need to rebuild PostgreSQL using --with-libxml.
