我有我需要比較的差異兩個XML文件的差異，XML是非常簡單的：比較兩個XML文件，並保存到結果文件
文件1：
<?xml version="1.0" encoding="utf-8"?>
<Feeds zone="my zone">
<Feed name="attribDump.json">ac1f07edc491a3d237cdfb1a17fc4551</Feed>
<Feed name="focus_GroupsKV.txt">0f9e0a14a4ffce6ff5065b6e088c1f84</Feed>
<Feed name="NAM_FORMATTED.csv">9e875496cdb072b5e54318d51295fdba</Feed>
<Feed name="BNP\activityTitles.txt">2d27c0f19b71b4b411bcb00011d3f8b0</Feed>
</Feeds>
和文件2 ：
<?xml version="1.0" encoding="utf-8"?>
<FeedsRequest version="1">
<Feeds zone="my zone">
<Feed name="attribDump.json">ac1f07edc491a3d237cdfb1a17fc4551</Feed>
<Feed name="focus_GroupsKV.txt">0f9e0a14a4ffce6ff5065b6e088c1f84</Feed>
<Feed name="BNP\activityTitles.txt">e54c5b851ee3ff3f43b10d24f2316431</Feed>
</Feeds>
</FeedsRequest>
文件1是對我們的文件共享和文件2個文件是使用斷開連接的設備，將需要的清單列表從文件1.刷新我需要有1支票）確保所有的 文件1中的提要位於文件2和2中）確保找到的所有提要具有相同的hashCode（長字符字符串）。一旦檢查完成後，我需要創建一個響應文件，其中包含所有提要的列表，然後指定每個提要的屬性（文件已找到並匹配），缺少（找不到文件），或更新（文件被發現，但它是一箇舊版本）。
所以基本上結果文件將如下這樣：
<?xml version="1.0" encoding="utf-8"?>
<FeedsResponse version="1">
<Feeds zone="my zone">
<Feed name="attribDump.json" status="ok">ac1f07edc491a3d237cdfb1a17fc4551</Feed>
<Feed name="focus_GroupsKV.txt" status="ok">0f9e0a14a4ffce6ff5065b6e088c1f84</Feed>
<Feed name="NAM_FORMATTED.csv" status="missing">afd2c620053ed4f85ab02b4cc5f7a2b2</Feed>
<Feed name="BNP\activityTitles.txt" status="updated">90805b851ee3ff3f43b10d24f2316431</Feed>
我在做什麼目前通過所有文件的循環在文件1，然後檢查他們對文件2的差異。在我被困住的地方，自從我使用過XML以來，已經有一段時間了，是如何構建響應文檔的。
FileInfo feedList = new FileInfo(_feedList);
FileInfo feedRequest = new FileInfo(_feedRequest);
// Load the documents
XmlDocument feedListXmlDoc = new XmlDocument();
feedListXmlDoc.Load(_feedList);
// Load the documents
XmlDocument feedRequestXmlDoc = new XmlDocument();
feedRequestXmlDoc.Load(_feedRequest);
//create response doc
XmlDocument feedResponseXmlDoc = new XmlDocument();
// Define a single node
XmlNode feedListNode;
XmlNode feedRequestNode;
// Get the root Xml element
XmlElement feedListRoot = feedListXmlDoc.DocumentElement;
XmlElement feedRequestRoot = feedRequestXmlDoc.DocumentElement;
// Get a list of all player names
XmlNodeList feedListXml = feedListRoot.GetElementsByTagName("Feed");
XmlNodeList feedRequestXml = feedRequestRoot.GetElementsByTagName("Feed");
// Create an XmlWriterSettings object with the correct options.
XmlWriter writer = null;
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.IndentChars = (" ");
settings.OmitXmlDeclaration = false;
// Create the XmlWriter object and write some content.
writer = XmlWriter.Create(_resultPath, settings);
writer.WriteStartElement("FeedsDiff");
// The compare algorithm
bool feedMatch = false;
int j = 0;
try
{
// loop through list of current feeds
for (int i = 0; i < feedListXml.Count; i++)
{
feedListNode = feedListXml.Item(i);
string feedListName = feedListNode.Attributes["name"].Value.ToString();
string feedListHash = feedListXml.Item(i).InnerText.ToString();
//check feed request list for a match
while (j < feedRequestXml.Count && feedMatch == false)
{
feedRequestNode = feedRequestXml.Item(j);
string feedRequestName = feedRequestNode.Attributes["name"].Value.ToString();
//checks to see if feed names match
if (feedListName == feedRequestName)
{
feedMatch = true;
string feedRequestHash = feedRequestXml.Item(j).InnerText.ToString();
//since we found the node, we can remove it from the request list
XmlNode node = feedRequestNode.ParentNode;
node.RemoveChild(feedRequestNode);
//checks to see if hash codes match
if (feedListHash == feedRequestHash)
{
//if name and code match, move to the next one
feedMatch = true;
//add 'status="ok"' attribute to the node
//feedResponseXmlDoc.ImportNode(feedRequestNode,false);
Debug.WriteLine(feedListName + " name and hash match");
j = 0;
}
else
{
feedMatch = true;
//feed has been updated since last device sync
//need to add status='update' attribute and append file to response
Debug.WriteLine(feedListName + " name matched but hash did not");
}
}
else
{
//names didn't match
//add status="missing" to the node
j++;
}
}
feedMatch = false;
}
// end Xml document
writer.WriteEndElement();
writer.Flush();
}
finally
{
if (writer != null)
writer.Close();
}
現在，我試圖實例循環之前的響應文檔，然後只需添加的元素，因爲他們被發現，但我有一個很難找到一個簡潔的方式來做到這一點。任何幫助表示讚賞。
你能證明你的代碼的，是有關您已發佈的問題..？ – MethodMan
按要求添加。我知道它在循環內有點薄，這就是我卡住的地方。 – TrevorGoodchild
