问题 I have built a little crawler and now when trying it out i found that when crawling certain sites my crawler uses 98-99% CPU. I used dotTrace to see what the problem could be and it pointed me towards my httpwebrequest method - i optimised it a bit with the help of some previous questions here on stackoverflow.. but the problem was still there. I then went to see what URLs that were causing the CPU load and found that it was actually sites that are extremely large in size - go figure :) So,

问题 Is there a reference/guide for using HTML Agility Pack on WP7.5? I tried compiling the source on my VS2010 but I wasn't able to reference the DLL created on my local machine. Basically, I'm looking for a text extractor to obtain the text from a given URL. I understand that the HTML Agility Pack works best. Any ideas/suggestions? Thanks :) 回答1: Yes, I was the one who created that discussion. As said in that discussions page, the solution to this problem is to reference the System.Xml.XPath DLL

问题 I have tried several combinations without success. The full xpath to that data is .//*[@id='detail_row_seek_37878']/td The problem is the number portion '37878' changes for each node and thus I can't use a foreach to loop through the nodes. Is there some way to use a wildcard and reduce the xpath to .//*[@id='detail wildcard , in an effort to bypass the absolute value portion? I am using html agility pack on this. HtmlNode ddate = node.SelectSingleNode(".//*[@id='detail_row_seek_37878']/td");

It's got to be noticed that the version of HAP is 1.4.6 but not 1.4.9 (tha latest one), because it cannot be installed from NuGet (just doesn't add reference) and I've found no links to download it manually. In old windows phone 8 silverlight app everything worked great. Please, help. 回答1: Use
