Hi,
I am using xpath_table to convert elements from an XML column to "rows".
Now according to
http://www.postgresql.org/docs/8.3/static/xml2.html
this function will be removed in a future version.
That chapter also claims that the new XML syntax covers the functionality of the xml2 module, but I cannot find a way
toreturn the elements of an XML document as rows (as xpath_table does)
Suppose I have the following content in my xml column:
<team>
<member id="10" name="Arthur Dent"/>
<member id="11" name="Ford Prefect"/>
</team>
I am using a statement similar to this:
select member_id, member_name
from xpath_table('id', 'xml_text', 'xmltest', '/team/member/@id|/team/member/@name', 'true')
as t(id integer, member_id varchar, member_name varchar)
to get the following output
member_id member_name
10 Arthur Dent
11 Ford Prefect
How would I achieve the same without using the deprecated xml2 module?
Thanks in advance
Thomas
