在这里，我想从父项中删除所有子项，这意味着从产品父节点中删除所有类别子节点特定类别子节点。

Here i want to remove all child from parent it means remove all category child node from product parent node except specific category child node.

XmlDocument doc = new XmlDocument（）;

XmlDocument doc = new XmlDocument();

doc.LoadXml（strxmlstring）;

XmlNodeList childNode = doc.SelectNodes（" // category"）;

doc.LoadXml(strxmlstring);
XmlNodeList childNode = doc.SelectNodes("//category");

foreach（childNode中的XmlNode节点）

       ;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP; {

&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP ;&NBSP;&NBSP; node.ParentNode.RemoveChild（node）;

foreach (XmlNode node in childNode)
                    {
                        node.ParentNode.RemoveChild(node);

除（< category>< code-id type =" pub"> e00002< / code-id>< title> test34< / title>< ranking> 160< / ranking>< / category>"）; &NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;

except( "<category><code-id type="pub">e00002</code-id><title>test34</title><ranking>160</ranking></category>") ;                 

}

推荐答案

试试这个：

XmlNode product = doc.SelectSingleNode( "/Product" );
foreach( XmlNode category in product.SelectNodes( "category[code-id!='e00002']" ) )
{
   product.RemoveChild( category );
}
