比方說,我有一個XmlNode的:如何從XmlNode中刪除文本?
<A>1</A>
如何從中刪除文本,所以我得到:的
<A />
代替:
<A></A>
下面是一個單元測試,顯示了我到目前爲止所嘗試的。
[Test]
public void RemoveXmlTextTest()
{
string xmlString = @"<B><A>1</A></B>";
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlString);
XmlNode testNode = doc.SelectSingleNode("//A");
//1. Set innerText to string.Empty - not working
//testNode.InnerText = String.Empty;
//2. Call removeAll - not working
//testNode.RemoveAll();
//3. testNode has one child with name '#text' - remove it - not working
//testNode.RemoveChild(testNode.FirstChild);
//4. Replace node with a new empty one - working but extremally ugly :(
//All references to testNode still points to the old one !!!!
testNode.ParentNode.ReplaceChild(doc.CreateElement(testNode.Name), testNode);
//Is there some better way to do it?
testNode = doc.SelectSingleNode("//A");
Assert.AreEqual("<A />", testNode.OuterXml);
}
