Html Agility Pack ── 一个解析HTML的工具

.NET 框架类库本身没有提供工具分析HTML，以前常用的做法是用正则表达式，或者浏览器控件，或者MSHTML组件，甚至SgmlReader。SgmlReader可以将HTML转化成XML，然后你就可以使用System.Xml命名空间下的类对文件进行查询。

CodePlex上有一个Html Agility Pack项目，是原生的.NET项目，不依赖MSHTML或者ActiveX/COM 对象。其中的HtmlDocument可以加载任何HTML文件(即使该文件是不well-formed的HTML)，然后允许你使用类似于System.Xml的对象模型对文件进行查询。

官网地址：www.codeplex.com/htmlagilitypack

例如：

HtmlWeb webClient = new HtmlWeb();
HtmlDocument doc = webClient.Load("file.htm");
HtmlNodeCollection nodes = doc.DocumentElement.SelectNodes("/html[1]/body[1]/div")
foreach(HtmlNode node in nodes)
{
Console.WriteLine(node.InnerText.Trim());
}
doc = null;
webClient = null;
nodes = null;

Q: 如何选择HTML结点？
//根据层次结构因为HTML具阶层性(Hierarchy)
HtmlNode node1 = doc.DocumentNode.SelectSingleNode("/html[1]/body[1]/div[1]/div[2]/div[7]/div[1]/div[3]/ol[1]/li[1]/div[1]/div[2]/address");
HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("/html[1]/body[1]/div[1]/div[2]/div[3]/div[2]/div[1]/div[1]/div[1]/div");
//根据ID
HtmlNode node2 = doc.DocumentNode.SelectSingleNode("//p[@id='prop_detail_qt_prop_1' ");

Publisher’s notes: PowerGREP is a powerful Windows grep tool. Quickly search through large numbers of files on your PC or network, including text and binary files, compressed archives, MS Word documents, Excel spreadsheets, PDF files, OpenOffice files, etc. Find the information you want with powerful text patterns (regular expressions) specifying the form of what you want, instead of literal text. Search and replace with one or many regular expressions to comprehensively maintain web sites, source code, reports, etc. Extract statistics and knowledge from logs files and large data sets.
•Learn how you can find information faster and comprehensively maintain large sets of files with PowerGREP.

How to use(Regular expression):
1. Include folders and subfolders which you want to search.
2. Fill file types( like *.cpp, etc) in Include files.
3. You also can filter File Modification Dates and File Sizes.
4. Select the Action Tab, then fill in the regular expressions.
5. Click the Search (Ctrl +F9)

Thanks,
