Обсуждение: Install XML on Postgres 8.1

Hi,
I need to install XML on Postgres 8.1.
What's the simples steps that I can follow?
I found on the internet, but there are many versions, packages and ways
to install.
What's the right way to install?

Can we compare the same powerful like Oracle has on Xml?

If you could help me!!
Thanks in advance.

XML support is provided in PostgreSQL via a contrib module xml2.
look for xml related folders in contrib folder after untarring the pgsql
source. go through the README files on contrib modules to
know the features.

The functionality of the xml2 contrib module is almost completely
orthogonal to what the SQL standard says in matters of XML.  Whether
either of these are equally "powerful" as what Oracle offers, I can't
say, but since we're currently working on enhanced XML functionality in
8.3, I invite comments on that.

xml2 is just a contrib package. for installing any contrib package
go to contrib folder. read the README file for instructions.
still if you have problem come back here.
sorry i do not know of a tutorial at the moment , but its easy.

PS: please stick to the discussion on the list only.

Dear Alexander,

After reading the thread and related resources it looks like xml
support in pgsql may undergo major changes.

hence i suggest that you  abstract the usage of pgsql for xml . so that it
is easy for you to change your app when the xml apis to pgsql changes.
this is easily accomplised by using your own functions that wrap the call
to contrib/xml2 functions. hope you get the point.

Indexing of data types is done in terms of operator classes (or maybe
operator families in 8.3, not sure), but so far no one has proposed to
define any operators whatsoever on the XML type, so I don't see where
any indexing mechanism would come from at the moment.  What does Oracle
offer?
