Re: [GENERAL] XML import with DTD

[Roy Walter]

It's not an xpath problem it's an XML import problem. Sorry if I wasn't 
clear.

Consider the following example queries. This one works fine:
   INSERT INTO wms_collection (docxml) VALUES (XMLPARSE(content(
   '<?xml version="1.0" encoding="ISO-8859-1"?>
   <shop>
   <product>Shoes</product>
   </shop>')))

This one does not:

   INSERT INTO wms_collection (docxml) VALUES (XMLPARSE(content(
   '<?xml version="1.0" encoding="ISO-8859-1"?>
   <!DOCTYPE publicwhip
   [
   <!ENTITY ndash   "&#8211;">
   <!ENTITY mdash   "&#8212;">
   ]>
   <shop>
   <product>Shoes</product>
   </shop>')))

Both are valid XML but the second query fails as follows:

   ERROR:  invalid XML content
   DETAIL:  Entity: line 2: parser error : StartTag: invalid element name
   <!DOCTYPE publicwhip
    ^
   Entity: line 4: parser error : StartTag: invalid element name
   <!ENTITY ndash   "&#8211;">
    ^
   Entity: line 5: parser error : StartTag: invalid element name
   <!ENTITY mdash   "&#8212;">

Subject: [GENERAL] XML import with DTD

Hi

I'm trying to use the XPath functionality of Postgres.

I can populate a text field (unparsed) with XML data but as far as I 
can see the xpath() function [now] only works on the xml data type.

When I try to populate a text field with XML data containing a DTD, 
however, the parser chokes. If I strip the DTD the parser chokes on 
undefined entities which are defined in the DTD.

(I switched the app' to from MySQL to Postgres because while MySQL 
works it returns matches in undelimited form which is next to useless 
if, for example, you return multiple attributes from a node.)

Does anyone know of  a solution to this problem?

Windows 2000 Server
Postgres 8.4

Roy Walter
