问题 I need to match words from lines. For example: The blue bird is dancing. Yellow card is drawn The day is perfect rainy blue bird is eating The four lines are in a text file l2 . I want to match the blue bird, yellow card, day and every time a line is printed that matched word is printed before the line. y=regexp(l2,('^(?=.*blue bird)|(?=.*day)|(?=.*Yellow card)$')); Is this how it works? I can't get the result. sprintf('[%s]',y,l2); 回答1: MATLAB's regex engine doesn't use \b as word boundary

问题 Overview: I am trying to combine two REGEX queries into one: \d+\.\d+\.\d+\.\d+ ^(?!(10\.|169\.)).*$ I wrote this as a two part query. The first part would isolate IPs in a block of text and after I copy and paste this I select everything and that does not being with a 10 or 169.

问题 I have a Outlook 2010 VBA script that should scan the body of selected non-delivery reports in my inbox and generates a text report if they match certain regular expressions in the body. Recently the script stopped working and it seems like I can no longer access the .body of the selected objects (debug.print outputs a lot of question marks to the immediate window). The script still works fine for regular (not NDR) emails in my inbox. I also noticed that the non-delivery reports all of a

问题 I having trouble implementing regex within xpath command. My goal here is to download the html contents of the main page, as well as the contents of all hyperlinks on the main page. However, the program throws exceptions because some of the href links do not connect to anything (ex. '//:javascript', or '#'). How would I use regex in xpath?

问题 I want to replace single occurrences of a character but not two in a string using C#. For example, I want to replace & by an empty string but not when the ocurrence is && . Another example, a&b&&c would become ab&&c after the replacement. If I use a regex like &[^&] , it will also match the character after the & and I don't want to replace it. Another solution I found is to iterate over the string characters. Do you know a cleaner solution to do that? 回答1: You can match both & and && (or any
