C#通过XML节点属性/属性值读取写入XML操作代码实例
1.XML的内容如下：
<?xmlversion="1.0"encoding="utf-8"?>
<root>
<title>
<settingsid="0"name="显示文字">欢迎您！智慧服务，互动体验......</settings>
<settingsid="1"name="字体">微软雅黑</settings>
<settingsid="2"name="颜色">Yellow</settings>
<settingsid="3"name="字体尺寸">48</settings>
</title>
<menu>
<submuid="0"name="部门分布"/>
<submuid="1"name="宣传视频"/>
<submuid="2"name="部门宣传"/>
<submuid="3"name="会议安排"/>
</menu>
<mu1>
<submuid="0"name="iCentroView产品">
<videoid="0">Videos/ICV.mp4</video>
</submu>
<submuid="1"name="员工社区">
<videoid="0">Videos/ygsqxcp.mp4</video>
</submu>
<submuid="2"name="三维展示">
<videoid="0">Videos/iBaosight.mp4</video>
</submu>
<submuid="1"name="好生活宣传">
<videoid="0">Videos/goodlift.mp4</video>
</submu>
</mu1>
<main>Picture/main.jpg</main>
</root>
2.获得XML文档
privatestaticstringurl=AppDomain.CurrentDomain.SetupInformation.ApplicationBase+"Config\\config.xml";
private XmlDocumentxmlDoc;
privateXmlNoderoot;
publicstaticstringTitle;
public XMLHandler()
{
xmlDoc=newXmlDocument();
LoadConfig();
}
private voidLoadConfig()
{
try
{
xmlDoc.Load(url);
root=xmlDoc.SelectSingleNode("root");
}
catch(Exceptione)
{
throwe;
}
}
3.通过属性名称读取XML节点中的内容
4.通过属性读取XML中节点的属性值 5.通过节点获取XML节点中的内容
publicTitleModelGetTitle()
{
try
{
TitleModeltitle=newTitleModel();
XmlNodenode=root.FirstChild;
if(node!=null)
{
foreach(XmlNodendinnode.ChildNodes)
{
XmlElementelement=(XmlElement)nd;
if(element.GetAttribute("name")=="显示文字")
{
title.Title=nd.InnerText;
}
elseif(element.GetAttribute("name")=="字体尺寸")
{
title.FontSize=Convert.ToInt32(nd.InnerText);
}
elseif(element.GetAttribute("name")=="颜色")
{
title.FontColor=FontColor(nd.InnerText);
}
elseif(element.GetAttribute("name")=="字体")
{
title.FontFamily=nd.InnerText;
}
}
}
returntitle;
}
catch(Exceptione)
{
throwe;
}
}
publicList<string>GetMenuString()
{
try
{
List<string>list=newList<string>();
XmlNodemenu=root.ChildNodes[1];
if(menu!=null)
{
foreach(XmlNodenodeinmenu.ChildNodes)
{
XmlElementelement=(XmlElement)node;
list.Add(element.GetAttribute("name"));
}
}
returnlist;
}
catch(Exceptione)
{
throwe;
}
}
publicstringGetMainBackground()
{
stringurl="Images/mainjpg";
try
{
XmlNodenode=root.LastChild;
if(node!=null)
{
url= node.InnerText;
}
returnurl;
}
catch(Exceptione)
{
throwe;
}
}
