求解 asp.net 对xml的操作
<?xml version="1.0" encoding="utf-8" ?>
<Table>
<Row >
<Title>首页</Title>
<Name>企业首页</Name>
<Href>_self</Href>
<Url>index.html</Url>
<Mark>index</Mark>
</Row>
<Row >
<Title>产品展示</Title>
<Name>产品展示</Name>
<Href>_self</Href>
<Url>Pro.html</Url>
<Mark>Pro</Mark>
</Row>
</Table>

怎么通过 <Mark>的值返回父节点中的所有节点。也就是说，当我接收<Mark>值为index时，把
<Title>首页</Title>
<Name>企业首页</Name>
<Href>_self</Href>
<Url>index.html</Url>
<Mark>index</Mark>
以上内容返回到Dataset中

[解决办法]

C# code

        string strXml = @"<Table>                              <Row >                              <Title>首页</Title>                                <Name>企业首页</Name>                                <Href>_self</Href>                                <Url>index.html</Url>                                <Mark>index</Mark>                                </Row>                              <Row >                              <Title>产品展示</Title>                                <Name>产品展示</Name>                                <Href>_self</Href>                                <Url>Pro.html</Url>                                <Mark>Pro</Mark>                                </Row>                              </Table>";        XmlDocument xdoc = new XmlDocument();        xdoc.LoadXml(strXml);        string strXPath = "/Table/Row[Mark='index']";        XmlNodeList oXmlNodes = xdoc.SelectNodes(strXPath);        //*************已经成取到所需的信息了***********        xdoc = new XmlDocument();        XmlDeclaration xmlDec = xdoc.CreateXmlDeclaration("1.0", "utf-8", null);        XmlElement rootNode = xdoc.CreateElement("Table");        xdoc.InsertBefore(xmlDec, xdoc.DocumentElement);        xdoc.AppendChild(rootNode);        foreach (XmlNode node in oXmlNodes)        {            XmlElement xmlNew = xdoc.CreateElement("Row");            xmlNew.InnerXml = node.InnerXml;            rootNode.AppendChild(xmlNew);        }        DataSet ds = new DataSet();        StringReader stream = new StringReader(xdoc.InnerXml);        XmlTextReader reader = new XmlTextReader(stream);        ds.ReadXml(reader);
