XmlDocument InnerXmlの整形


XmlDocument doc = new XmlDocument();
doc.LoadXml(
"<test><data><hoge>abc</hoge><a>def</a></data></test>"
);
DataSet ds = new DataSet();
ds.ReadXml(new StringReader(doc.InnerXml));
StringBuilder sb= new StringBuilder();
ds.WriteXml(new StringWriter(sb));
Console.WriteLine(sb.ToString());

出力結果
<test>
  <data>
    <hoge>abc</hoge>
    <a>def</a>
  </data>
</test>
