Still having problems with NameSpaceManage r

[Chris]

Hi,

I'm trying to extract data from objects that contain xml that fits a
third party schema with it's own root namespace. I've added a
namespace manager that seemed to work most of the time but I never
fully understood why. I've now hit another problem. It might be code
blindness but I can't see why it doesn't work.

I am trying to select a node using XPath from an XmlElement

XmlElement xEntityNode ;

/* xEntityNode's OuterXml is this
<facilityList xmlns="qvEntity Types">
<facility>
<internalId>6 </internalId>
<description>Or derOnLine</description>
<displayOrder>1 </displayOrder>
</facility>
<facility>
<internalId>7 </internalId>
<description>Co nfirmHeldOrders </description>
<displayOrder>1 </displayOrder>
</facility>
<facility>
<internalId>2 8</internalId>
<description>Vi ewProductStock</description>
<displayOrder>1 </displayOrder>
</facility>
<facility>
<internalId>2 9</internalId>
<description>Se eOtherUsersOrde rs</description>
<displayOrder>1 </displayOrder>
</facility>
<facility>
<internalId>3 0</internalId>
<description>Bu y</description>
<displayOrder>1 </displayOrder>
</facility>
</facilityList>
*/

// Here's my code
nsmgr = new XmlNamespaceMan ager( new System.Xml.Name Table() );
nsmgr.AddNamesp ace("qv", "qvEntityTypes" ) ;
XmlNode propertyNode = xEntityNode.Sel ectSingleNode(
"//qv:facilityList/qv:facility[description = \"Buy\"]" , nsmgr);

// END

SelectSingleNod e returns null. I think the namespace applies to the
nested facility level hence the qv:facility.

Can anyone suggest a better way of dealing with the namespace?

It might be code blindness but I can't see why it doesn't work.
Definitely code blindness. ;-)

: : XmlNode propertyNode = xEntityNode.Sel ectSingleNode(
"//qv:facilityList/qv:facility[description = \"Buy\"]" , nsmgr);

The XPathExpression that successfully returns a node is,

//qv:facilityList/qv:facility[qv:description = 'Buy']

The prefix that you correctly used on each of the location
steps is also required on the child element, description, in
the expression's predicate.

Oh yeah. Should have tried that. Thanks :-)
