如何使用 XPath 只选择“失败”值?
<Properties>
<Property Descriptor="100">1377349460.298</Property>
<Property Descriptor="101">1</Property>
<Property Descriptor="24000">fail</Property>
</Properties>
<Properties>
<Property Descriptor="100">1377349462.298</Property>
<Property Descriptor="101">1</Property>
<Property Descriptor="24000">pass</Property>
</Properties>
我试过Property[@Value="fail"]
了,但它不起作用。
