XPath function:contains Error(if I use it)!

xml：

<Root>
   <MyNode>
         <Name>东方a96</Name>
         <Status>0</Status>
   </MyNode>
   <MyNode>
          <Name>西方b92</Name>
          <Status>0</Status>
    </MyNode>
    <MyNode>
          <Name>东方a88</Name>
          <Status>0</Status>
     </MyNode>
</Root>

Code：

#import <msxml3.dll> named_guids
using namespace MSXML2;

......
strPath = CString(_T("/Root/MyNode[contains(Name,'a')]"));
pNodeList = m_pXmlQueryDoc->selectNodes((_bstr_t)strPath); 
......

BTW：if i don't use xpath function, there is no error.I have tested some xpth function,only string function can use,ohers all error at selectNodes line.

You need to add this to your code:

setProperty(BSTR strProp, VARIANT strVal);

where:

strProp 
    A BSTR string whose value is "SelectionLanguage".
strVal 
    A VARIANT string, whose value is  "XPath".

When not specified, the default is "XSLPattern" -- and this means that XPath isn't turned on at all.
