下面我有我从Web服务接收到的XML。我在C＃中使用XML真的很新，但我试图仅在<data_text>元素来自<form_id>。我想通过遍历所有的XML来写入SQL发送的内容。有没有简单的方法来设置这个，所以我可以找到<data_text>说从一个特定的<field_number>并分配给一个字符串，然后使用该字符串写入SQL？一旦我可以将所有东西都写入字符串，我可以轻松地写入SQL，但是我无法将XML读入字符串。我也愿意接受其他选择。在最底层，我拥有目前C＃的位置，就我而言，目前为止。在C中读取多个XML元素并写入SQL＃

一些C＃-code
protected void GetMessages()
{
XmlDocument xmldoc = new XmlDocument();
xmldoc.PreserveWhitespace = false;
Regex regex = new Regex(@"^\s+$[\r\n]*");
String cleanedXml = regex.Replace(postXMLData(URL, prefix, "POST"), "><").TrimStart();
xmldoc.LoadXml(cleanedXml);
XmlNodeList messageList = xmldoc.GetElementsByTagName("imessage");
foreach (XmlNode node in messageList)
{
XmlElement messageElement = (XmlElement)node;
String Arrival;
Arrival = messageElement.GetElementsByTagName("data_text")[0].InnerText;
testTxtBx.Text += Arrival; //I am just trying to write to a Textbox now to see the results.
}
}
请exaplin你需要什么，你的问题是不明确你要分析这个XML在C＃或你想在SQL中解析？ –
嗨，你的编辑带走了我的......在你的文字中，所有'都是隐形的。你必须把它们包装起来。否则，这个问题是完全不清楚的...... –
