求助！关于xpath 检索XML的问题！！
各位：
我用xpath 语句是：
ds = xmlTool.GetData( "//m[@l=\ "欧洲联赛冠军杯\ "] ");
想提取所有的l=“欧洲联赛冠军杯”的节点。
语句已经成功！但是在ds中只有一行数据。是我xpath写的不对，还是下面的提取方法有问题。提取方法：
————————————————————————————————
public DataSet GetData(string XmlPathNode)
{
DataSet ds = new DataSet();
StringReader read = new StringReader(objXmlDoc.SelectSingleNode(XmlPathNode).OuterXml);
ds.ReadXml(read);
return ds;
}
————————————————————————————————————
XML格式是：
——————————————————————————————————
<?xml version= "1.0 " encoding= "gb2312 " ?>
<g>
<s>
<m i= "218057 " l= "新加坡职业联赛 " c= "#FF99CC " a= "雅龙联 " b= "卡沙 " d= "2007,07,31,19,45 " tv= " " as= " " bs= " " ah= " " bh= " " ar= " " br= " " st= "未开赛 " />

[解决办法]
ds = xmlTool.GetData( "//m[@l=\ "欧洲联赛冠军杯\ "] ");
==>
ds = xmlTool.GetData( "g/s/m[@l= '欧洲联赛冠军杯 '] ");
[解决办法]
其实楼主先把数据读取到dataset，然后在dataset中过滤更方便。
DataSet ds = new DataSet();
ds.ReadXml(@ "f:\a.xml ");
ds.Tables[ "m "].DefaultView.RowFilter = "l= '欧洲联赛冠军杯 ' ";
[解决办法]
for dataset and xml, use XmlDataDocument
[解决办法]
SelectSingleNode
只取第一个节点。见名之意，楼主一定大意了。
