一．Xml文件
二．IXMLDOMDocument/DOMDocument簡介
2．1 屬性
2．1．1 parseError
2．1．2 async.
2．1．3 xml
2．1．4 text 3
2．1．5 attributes
2．1．6 nodeName
2．1．7 documentElement
2．1．8 nextSibling
2．1．9 childNodes
2．1．10 firstChild
2．1．11 lashChild
2．2 方法
2．2．1 loadXML
2．2．2 load
2．2．3 selectSingleNode
2．2．4 selectNodes
2．2．5 getElementsByTagName
2．2．6 hasChildNodes
三．例子
一．Xml文件
<?xml version="1.0"?>
<book level="1">
<Name>c++</Name>
<Price>20</Price>
<info>
<k>1</k>
</info>
<info>
<k>2</k>
</info>
</book>
在asp.net下實現代碼：
string str = Server.MapPath("test1.xml");
XmlTextWriter xmlWriter = new XmlTextWriter(str,null);
xmlWriter.Formatting = System.Xml.Formatting.Indented;
xmlWriter.WriteStartDocument();
xmlWriter.WriteStartElement("book");
xmlWriter.WriteAttributeString("level","1");
xmlWriter.WriteElementString("Name","c++");
xmlWriter.WriteElementString("Price","20");
xmlWriter.WriteStartElement("info");
xmlWriter.WriteElementString("k","1");
xmlWriter.WriteEndElement();
xmlWriter.WriteStartElement("info");
xmlWriter.WriteElementString("k","2");
xmlWriter.WriteEndElement();
xmlWriter.WriteEndElement();
xmlWriter.WriteEndDocument();
xmlWriter.Close();
二．IXMLDOMDocument/DOMDocument簡介
2．1 屬性
2．1．1 parseError
Returns an IXMLDOMParseError object that contains information about the last parsing error
返回解析錯誤時的一個對象。
重要的有parseError.errorCode,parseError.reason
如果load時路徑不對，會返回“系統未找到指定的對象”的錯誤
2．1．2 async
Specifies whether asynchronous download is permitted
是否允許異步下載，布爾值
2．1．3 xml
Contains the XML representation of the node and all its descendants. Read-only.
該點及下面派生的所有點的全部信息，只讀如果要求book點的xml,返回“<book level="1"><Name>c++</Name><Price>20</Price><info><k>1</k></info><info><k>2</k></info></book>”，如果Name的xml，返回“<Name>c++</Name>”
