问题 I trying to parse a string in an XML node by using an XPath query which requires that I strip out a substring and read the remaining value. The substring may have a dynamic amount of whitespace before and after it before I can get to the value, so it would be helpful to have some sort of a indexOf function to use in the XPath. I'm trying to use substring-after, but there is a good chance the XPath is 1.0, which according to this post might make this more difficult to accomplish. The following

问题 I'm looking to apply a KMP (or similar) search to a large file (> 4GB). I'm expecting this to give me problems though.I can't copy it all to memory because there isn't enough space there. My question is, what is the best way to go about doing this search? Should I simply create a FILE* and do the search directly in the file, should I copy blocks (say 4k) to memory and search those, or something else completely? 回答1: If you are using a platform that supports it, you can use mmap().

问题 Is there a way to search the twitter api using a regular expressions? The expression I need to match is for a stock name. /\$[a-zA-Z]{1,5}/ 回答1: No, and as for the reason, you have to look at it from an architectural standpoint. Given the volume that Twitter has using the API, they would have to do the regex match against all possible tweets that are searchable. That is an insane amount of data processing. 回答2: Well, it appears to have been possible in 2009: http://granades.com/2009/04/06

If I try to make a query using a string other than *:* , such as test , no

I am using Visual Studio to debug a large multithreaded C++ application. I am trying to find out what thread ran a function I am interested in. I have more than 40 threads, some with really lengthy call stacks. So, manually inspecting individual call stacks to see if they contain my function is really tedious.

问题 Could some one point me to a tutorial on how to work with the Eclipse search plug-in with custom views in an Eclipse RCP program.
