问题 Can I parse an HTML file using an XML parser? Why can('t) I do this. I know that XML is used to store data and that HTML is used to display data. But syntactically they are almost identical.

问题 I need to get the generated HTML source of the page after JS DOM manipulation has all been done. I was using Phantomas https://github.com/macbre/phantomas for this purpose, but unfortunately it does not provide a way to pass in request headers.

问题 How can one parse HTML/XML and extract information from it? 回答1: Native XML Extensions I prefer using one of the native XML extensions since they come bundled with PHP, are usually faster than all the 3rd party libs and give me all the control I need over the markup.

问题 I'm trying to build an iPad app to download and display documents (pdf, ppt, doc, etc.) from a web server. Currently it does this by parsing the HTML structure (using hpple ) on the server. For example, the files are held at: Http://myserver.com/myFolders/myFiles/ The app goes to this location and traverses the tree, using an X-Path query, e.g. "/html/body/ul/li/a" It then downloads whatever documents it finds to the iPad for display. So far this works quite well but the server is publicly

问题 I would like to make a program that parses the html page and selects useful information and displays it. I did it by opening a stream and then line by line searching for this appropriate content, but this is a time consuming process.
