当然不是。您可以使用
doc.SelectNodes（" // namespace :: *"）选择名称空间声明。

嗨;
这种方式有效。我在文件的标题中声明了3个名称空间。
SelectNodes（" // namespace :: *"）给了我36个节点。我没有检查每一个
但它似乎是一遍又一遍地重复的3个命名空间。
任何想法为什么我没有得到只是3 ？

谢谢 - 戴夫

Hi;
This sort-of worked. I have 3 namespaces declared in the header of the file.
The SelectNodes("//namespace::*") gave me 36 nodes. I did not check each one
but it appeared to be the 3 namespaces repeated over and over.
Any idea why I didn''t get just 3?
