struggling with XML namespace nodes query

[fteamdns]

I'm struggling to get my head around XML namespace query when using XML nodes - I've read other similar questions here and an article here but cannot apply this to my specific query.I have a larger version of this sample XML:SELECT CAST('<Navigator clsid="{ABF8EB05-610D-11D3-A53E-684F745C}"> <Version>7</Version> <NavigatorNodes clsid="{0484ACB1-78F5-48D7-A26B-3A0ACD3A5F91}"> <NavigatorNode clsid="{59AB61BD-7833-4954-94C2-B6D737E3DD6F}"> <Indent>0</Indent> <Caption>Contact</Caption> <Selected>0</Selected> <ViewType>0</ViewType> <ViewSubType>0</ViewSubType> <ShowTotals>0</ShowTotals>

trying queries to get to the information contained within the a1:Condition Node. I've tried queries such as:;WITH XMLNAMESPACES('http://www.ascenttechnology.co.uk/schemas/services' AS a1,'http://www.ascenttechnology.co.uk/schemas/entities' AS a2,DEFAULT 'http://www.w3.org/21/XMLSchema-instance')SELECT #xmldata.*,ref.value('attribute_name[1]','NVARCHAR(50)') as attribute_nameFROM #xmldataCROSS APPLY xmldata.nodes('/Navigator/NavigatorNodes/NavigatorNode/a1:QueryFilter/a1:ConditionCollection/a1:Condition') T(ref)But they're always coming back blank when I get near the namespaced nodes - I'm able to pull data from the nodes all the way up to '/Navigator/NavigatorNodes/NavigatorNode' but then have no luck.Thanks!
