下面我有我從Web服務接收到的XML。我在C＃中使用XML真的很新，但我試圖僅在<data_text>元素來自<form_id>。我想通過遍歷所有的XML來寫入SQL發送的內容。有沒有簡單的方法來設置這個，所以我可以找到<data_text>說從一個特定的<field_number>並分配給一個字符串，然後使用該字符串寫入SQL？一旦我可以將所有東西都寫入字符串，我可以輕鬆地寫入SQL，但是我無法將XML讀入字符串。我也願意接受其他選擇。在最底層，我擁有目前C＃的位置，就我而言，目前爲止。在C中讀取多個XML元素並寫入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.
}
}
請exaplin你需要什麼，你的問題是不明確你要分析這個XML在C＃或你想在SQL中解析？ –
嗨，你的編輯帶走了我的......在你的文字中，所有'都是隱形的。你必須把它們包裝起來。否則，這個問題是完全不清楚的...... –
