本文介绍了无法生成XML差异的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试使用Microsoft.XmlDiffPatch找到xml差异。但我没有得到完整的xml数据作为输出。它删除了xml数据的最后一部分。
这是代码
I try to find xml difference using Microsoft.XmlDiffPatch. But i did not get complete xml data as output. It removes last portion of xml data.
Here is the code
string FindXMLDiff(string oldXmlString, string newXmlString, out string xmlDiff)
{
string htmlOut = string.Empty; xmlDiff = "";
XmlDiff xmldif = new XmlDiff(XmlDiffOptions.IgnoreChildOrder |
XmlDiffOptions.IgnoreNamespaces |
XmlDiffOptions.IgnorePrefixes |
XmlDiffOptions.IgnoreDtd |
XmlDiffOptions.IgnoreWhitespace);
System.IO.StringReader oldString = new System.IO.StringReader(oldXmlString);
System.IO.StringReader newString = new System.IO.StringReader(newXmlString);
System.Xml.XmlReader oldEReader = System.Xml.XmlReader.Create(oldString);
System.Xml.XmlReader newEReader = System.Xml.XmlReader.Create(newString);
StringBuilder diffElement = new StringBuilder();
System.Xml.XmlWriter diffWriter = System.Xml.XmlWriter.Create(diffElement);
bool bIdentical = xmldif.Compare(oldEReader, newEReader, diffWriter);
diffWriter.Close();
xmlDiff = diffElement.ToString();
System.Xml.XmlTextReader difReader = new System.Xml.XmlTextReader(new System.IO.StringReader(diffElement.ToString()));
System.Xml.XmlTextReader difReader1 = new System.Xml.XmlTextReader(new System.IO.StringReader(diffElement.ToString()));
System.Xml.XmlTextReader orgReader = new System.Xml.XmlTextReader(new System.IO.StringReader(oldXmlString));
System.Xml.XmlDocument diffgramDoc = new System.Xml.XmlDocument();
diffgramDoc.Load(difReader1);
XmlDiffView view = new XmlDiffView();
if (diffgramDoc.DocumentElement.ChildNodes.Count > 0)
{
view.Load(orgReader, difReader);
System.IO.MemoryStream stream = new System.IO.MemoryStream();
System.IO.StreamWriter sw1 = new System.IO.StreamWriter(stream);
sw1.Write("<html><body><table style='font-family:verdana; font-size:12'>");
sw1.Write("<tr><td>Legend: <font style='background-color: yellow'" +
" color='black'>added</font> <font style='background-color: red'" +
"color='black'>removed</font> <font style='background-color: " +
"lightgreen' color='black'>changed</font>" +
"</td><td><font style='background-color: red' color='blue'>moved from</font>" +
" <font style='background-color: yellow' color='blue'>moved to" +
"</font> <font style='background-color: white' color='#AAAAAA'>" + "ignored</font></td></tr>");
sw1.Write("<tr><td>Old");
sw1.Write("</td><td>New");
sw1.Write("</td></tr>");
view.GetHtml(sw1);
sw1.Write("</table></body></html>");
var sr = new System.IO.StreamReader(stream);
stream.Seek(0, System.IO.SeekOrigin.Begin);
htmlOut = sr.ReadToEnd();
sw1.Close();
}
else
{
htmlOut = "";
}
view = null;
oldString.Close();
newString.Close();
oldEReader.Close();
newEReader.Close();
diffWriter.Close();
difReader.Close();
orgReader.Close();
return htmlOut;
}
在htmlOut的值中有一些xml缺失。
In this values of "htmlOut" has some xml missing.
oldXmlString = "<?xml version=\"1.0\" encoding=\"utf-8\"?><MyXml xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" version=\"1.0.0.1\"><TableData><Parameters><Parameter name=\"Width\"><MinValue>10</MinValue><MaxValue>100</MaxValue></Parameter><Parameter name=\"Height\"><MinValue>40</MinValue><MaxValue>600</MaxValue></Parameter><Parameter name=\"Depth\"><MinValue>34</MinValue><MaxValue>250</MaxValue></Parameter></Parameters></TableData></MyXml>";
newXmlString = "<?xml version=\"1.0\" encoding=\"utf-8\"?><MyXml xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" version=\"1.0.0.1\"><TableData><Parameters><Parameter name=\"Width\"><MinValue>10</MinValue><MaxValue>100</MaxValue></Parameter><Parameter name=\"Height\"><MinValue>80</MinValue><MaxValue>600</MaxValue></Parameter><Parameter name=\"Depth\"><MinValue>34</MinValue><MaxValue>86</MaxValue></Parameter><Parameter name=\"Speed\"><MinValue>0</MinValue><MaxValue>10</MaxValue></Parameter></Parameters></TableData></MyXml>";
