Title: Working with XML.

Hi Theo,   I am not aware of any means of passing xml to stored procedures, apart from writing your own function to parse the xml.   In regard to your second question - how to access the second record - try using a more explicit xpath query incorporating a "where" component.  For example, if you wanted to access the second row based upon the value of cola, you could use '//query/[EMAIL PROTECTED]'525887']/text()'.  Or you could specify the position of the record if you know its position: '//query/row[2]/text()'.   Microsoft has a very good reference on xpath expressions: http://msdn.microsoft.com/library/default.asp?url="">.   Regards, George ----- Original Message ----- From: Theo Galanakis To: pgsql-sql@postgresql.org Sent: Sunday, February 13, 2005 11:48 PM Subject: [SQL] Working with XML. Hi Folks, Is there a way to pass in an xml string into a stored proc and thenplace this into a temp table? I use to be able to do this in sql server, it was quite handy as I could call one stored proc to update multiple records, here is a sample in sql server: select CoverTypeID, ItemSQ, SituationID, ItemDescription, CoverAmount From  OpenXML ( @XmlHandle, '/cover/covertype/item',1 )             With ( CoverTypeID int '../@id',                       ItemSQ int '@id',                       SituationID int '@situationID',                       ItemDescription varchar(100) '@description',                       CoverAmount money '@amount' ) I have managed to get get pgxml_xpath working, however Im not sure how to access specific rows in an xml document. E.g below there are two records, how do I access the second record, the following returns both ,'//query/row/cola values being (284122,525887): select pgxml_xpath( '<query columns="4" rows="100"><row><cola>284122</cola><colb>789648</colb><colc>{ts ''2005-02-14 16:13:18''}</colc><cold>unbnda8m5946z55sgi1xco34h1q9tLonoys3nyk1d5tgtLaw8h5wya0zdv7vigeiuk9xqLuacdy0dsisopb8g1o4o76090otmq65</cold></row<row><cola>525887</cola><colb>493253</colb><colc>{ts ''2005-02-14 16:13:18''}</colc><cold>6uydk442uz247ga45kpys7htkxznkn8La31qhn942wu2cu2pdr25mv2nup2zh3vcbh3c4vdauak3p3w093cvtkeyga692b455cr3</cold></row></query>' ,'//query/row/cola/text()','','') ______________________________________________________________________ This email, including attachments, is intended only for the addressee and may be confidential, privileged and subject to copyright.
