如何使用html敏捷包获取自定义标签? [英] How get a custom tag with html agility pack?
问题描述
需要创建摘要/索引
为此，我有标签<Document-Title> My Title </Document-Title>
如何使用HTML敏捷包获取这些标签?
How I get these tags using HTML agility pack?
我已经尝试过了:
HtmlDocument html = new HtmlDocument();
html.Load(new StringReader(Document.Content)); //Is the <html> I'm load in database
var titles = html.DocumentNode.SelectNodes("//Document-Title");
但是标题为空
推荐答案
只需使用//document-title，它就必须小写，HAP默认将标签小写，我相信原因是xHTML要求标签名称为小写字母，因此HAP可能认为，但不是特定于标准HTML，它可以很好地使用带有大写字母的标记.
Just use //document-title , it jsut need to be lowercase, HAP lowercases the tags by default, i believe the reason is that xHTML required the tag names to be lower-case, so HAP probably considered that, but its not specific to standard HTML, its fine to use tags with capitalization.
更新:经过一些研究后，小写是对xpath的要求，HAP本身对大小写敏感，并且不关心XHTML.
Update: after some research lower case is an xpath requirement, HAP is case insenstive on its own and does not care about XHTML.
