我想获取所有带有子元素值的 UpsData 元素,但我只有 UpsData 元素 id:
流 sw = CopyAndClose(response.GetResponseStream());
XmlTextReader rdr = new XmlTextReader(sw);
while (rdr.Read())
{
if (rdr.IsStartElement())
{
if (rdr.NodeType == XmlNodeType.Element)
{
if (rdr.Name == "UpsData")
{
rdr.MoveToAttribute("id");
if (rdr.Name == "Date")
{
ConsoleInfo(rdr.Value);
}
}
}
}
}
如何获取子元素值?谢谢!
