Question

我正在编写一个实用程序，按计划将evernote笔记导出到Outlook中。 Outlook API需要纯文本，而Evernote会输出纯文本注释的XHTML doc版本。我需要的是去除所有标签和unescape嵌入在Evernote导出文件中的源XHTML文档。

基本上我需要转身;

<note>
  <title>Test Sync Note 1</title> 
  <content>
  <![CDATA[ <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE en-note SYSTEM "http://xml.evernote.com/pub/enml.dtd">

<en-note bgcolor="#FFFFFF">
<div>Test Sync Note 1</div>
<div>This i has some text in it</div>
<div>&nbsp;</div>
<div>&nbsp;</div>
<div>and a second line</div>
</en-note>

  ]]> 
  </content>
  <created>20081028T045727Z</created> 
  <updated>20081028T051346Z</updated> 
  <tag>Test</tag> 
</note>

进入


    Test Sync Note 1
    This i has some text in it


    and a second line

我可以很容易地解析CDATA部分并获得4行文本，但是我需要一种可靠的方法去除div，unescape并处理可能已经偷偷摸摸的任何额外的HTML。

我假设有一些MS API组合可以完成这项工作，但我不知道。

Answer 1

我会使用正则表达式删除所有HTML标记，这个非常基本，我相信如果它不能正常工作，你可以调整它。

Regex.Replace("<div>your html in here</div>",@"<(.|\n)*?>",string.Empty);

Answer 2

您还可以使用xslt转换将xml转换为文本文档。

Answer 3

您可以使用HTML Agility Pack。

Answer 4

据我所知，没有任何事情可以执行该特定工作，但您可能希望查看使用XSLT或浏览IXPathNavigable。

        string xml = @"<note>
          <title>Test Sync Note 1</title> 
          <content>
          <![CDATA[ <?xml version=""1.0"" encoding=""UTF-8""?>
           <!DOCTYPE en-note SYSTEM ""http://xml.evernote.com/pub/enml.dtd"">

        <en-note bgcolor=""#FFFFFF"">
        <div>Test Sync Note 1</div>
        <div>This i has some text in it</div>
        <div> </div>
        <div> </div>
        <div>and a second line</div>

        ";
        XPathDocument doc = new XPathDocument(new StringReader(xml));
        XPathNavigator nav = doc.CreateNavigator();

        // Compile a standard XPath expression

        XPathExpression expr;
        expr = nav.Compile("/note/content");
        XPathNodeIterator iterator = nav.Select(expr);

        // Iterate on the node set

        try
        {
            while (iterator.MoveNext())
            {
                //Get the XML in the CDATA
                XPathNavigator nav2 = iterator.Current.Clone();
                XPathDocument doc2 = new XPathDocument(new StringReader(nav2.Value.Trim()));

                //Parse the XML in the CDATA
                XPathNavigator nav3 = doc2.CreateNavigator();
                expr = nav3.Compile("/en-note");
                XPathNodeIterator iterator2 = nav3.Select(expr);
                iterator2.MoveNext();
                XPathNavigator nav4 = iterator2.Current.Clone();

                //Output the value directly, does not preserve the formatting
                Console.WriteLine("Direct Try:");
                Console.WriteLine(nav4.Value);

                //This works, but is ugly
                Console.WriteLine("Ugly Try:");
                Console.WriteLine(nav4.InnerXml.Replace("<div>","").Replace("</div>",Environment.NewLine));
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
