Simple 'get elements by name' XPath question (in C#)

Perphaps someone can explain to me why I do not find what I expect with XPath in an XmlDocument. I have an XmlNode (called xml). If I run xml.OuterXml I get the following:

<MirrorAttributeChangeResponse xmlns="company/ws/shared/attribute">
<MirrorAttributeChangeResult>
<AttributeChange>
<FieldName>coloredfield</FieldName>
<AttributeName>style</AttributeName>
<AttributeValue>;background-color: red</AttributeValue>
<Overwrite>false</Overwrite>
</AttributeChange>
<AttributeChange>
<FieldName>coloredfield</FieldName>
<AttributeName>style</AttributeName>
<AttributeValue>;background-color: red</AttributeValue>
<Overwrite>false</Overwrite>
</AttributeChange>
<AttributeChange>
<FieldName>coloredfield</FieldName>
<AttributeName>style</AttributeName>
<AttributeValue>;background-color: red</AttributeValue>
<Overwrite>false</Overwrite>
</AttributeChange>
</MirrorAttributeChangeResult>
</MirrorAttributeChangeResponse>

If I run xml.SelectNodes("//AttributeChange") I expect to get the 3 AttributeChange nodes, but I get 0 nodes. Why? Does it have something to do with namespaces?

Thanks Gertone, that solved it. I hope it still performs about the same. It looks kind of expensive.

welcomr,

it IS expensive, hopefully your XML is not too big
If it is too expensive in your program, use a namespace manager
