XML文件格式如下:

<?xml version="1.0" encoding="utf-8"?>
<Resume xmlns="http://ns.test.com/resumes">
? <PersonalInformation>
??? <GeneralInformation>
????? <Name><![CDATA[張三]]></Name>
????? <Birthday>1978-06</Birthday>
????? <Gender>男</Gender>
??? </GeneralInformation>

? </PersonalInformation>

</Resume>

由于這個XML文件加了Xmlns命名空間,如果直接用xxx.SelectSingleNode("PersonalInformation/GeneralInformation/Name"),結果返回null;

解決辦法:

??????????????? XmlReaderSettings xs = new XmlReaderSettings();
??????????????? xs.XmlResolver = null;
??????????????? xs.ProhibitDtd = false;????????????????
??????????????? XmlReader xr = XmlReader.Create(sourceFile, xs);
??????????????? XmlDocument doc = new XmlDocument();
??????????????? doc.Load(xr);//載入源XML文件

????????????????XmlNamespaceManager nameSpace = new XmlNamespaceManager(doc.NameTable);
??????????????? nameSpace.AddNamespace("abc", "http://ns.test.com/resumes");???????????????

??????????????? XmlElement resume = doc.DocumentElement;

???????????????//讀取節點內容(要在節點前加命名空間前綴,如本例"abc:")

???????????????resume.SelectSingleNode("abc:PersonalInformation/abc:GeneralInformation/abc:Name", nameSpace).InnerText.Trim()
