hyperlink

问题 I want to crawl an entire website , I have read several threads but I cannot manage to get data in a 2nd level.

问题 There is a standard from Adobe that in theory specifies opening PDF documents from a link clicked in a browser in a way to open specific sections (AKA "anchor", "named reference") of PDF document. This functionality should be of great help if one would like to refer to a specific portion of large PDF (such as some standard or specification). However, from what I see now, support for this standard is close to non-existent. For example, these links should open Scala Reference PDF at section 3.2

问题 In TFS 2010 I have work items with linked changesets. I can generate a query that reports the work items I'm looking for.

问题 Is it possible to have a normal link pointing to the current location?

问题 I can't set my table row as link to something. I can use only css and html. I tried different things from div in row to something another, but still can't make it works. 回答1: You have two ways to do this: Using javascript: <tr onclick="document.location = 'links.html';"> Using anchors: <tr><td><a href="">text</a></td><td><a href="">text</a></td></tr> I made the second work using: table tr td a { display:block; height:100%; width:100%; } To get rid of the dead space between columns: table tr

问题 (http([s]?):\/\/?)(([a-zA-Z0-9]+(\.?))+)([a-zA-Z0-9]+((\.[a-zA-Z]{2,5}){1,2})((\/[a-zA-Z0-9\?&=_\-\~:/?#[\]@!\$&'()\*\+,;]*)*)((\.[a-zA-Z]{2,5}){0,2})) This is my regex which is working well for matching the links in the string.
