我正在使用下面的代码 XmlDiff 来比较两个 xml 文件。

XmlReader reader1 = XmlReader.Create(new StringReader(file1));
XmlReader reader2 = XmlReader.Create(new StringReader(file2));

string diffFile = "D:\\XMLDiffCompare\\XmlDiffFilename.xml";
StringBuilder differenceStringBuilder = new StringBuilder();

FileStream fs = new FileStream(diffFile, FileMode.Create);
XmlWriter diffGramWriter = XmlWriter.Create(fs);

// XmlTextWriter diffgram = new XmlTextWriter(Console.Out);
// diffgram.Formatting = Formatting.Indented;

XmlDiff xmldiff = new XmlDiff(XmlDiffOptions.IgnoreChildOrder );
bool bIdentical = xmldiff.Compare(file1, file2, false, diffGramWriter);

比较后生成的xml文件为:

<?xml version="1.0" encoding="UTF-8"?>
<xd:xmldiff xmlns:xd="http://schemas.microsoft.com/xmltools/2002/xmldiff" version="1.0" srcDocHash="12061993843110569490" options="IgnoreNamespaces " fragments="no">
  <xd:node match="2">
    <xd:node match="1">
      <xd:node match="2">
        <xd:node match="2">
          <xd:node match="1">
            <xd:change match="1">USA</xd:change>
          </xd:node>
        </xd:node>
      </xd:node>
    </xd:node>
    <xd:node match="2">
      <xd:node match="1">
        <xd:change match="1">7909</xd:change>
      </xd:node>
    </xd:node>
  </xd:node>
</xd:xmldiff>

我想获取 的节点名称"USA",也就是"countryName",并且还想忽略7909,这是一个时间戳。XML 文件有很多节点,这就是我想打印"CountryName"节点以查看值的原因。

此外,值为“7909”的节点属于名为tigin的命名空间xmlns:tig="...",我不介意忽略tig文档中包含 namspace 的所有内容。但是我不确定在比较过程中如何抑制它。
