ruby - Strip words beginning with a specific letter from a sentence using regex -


I'm not sure how to use regular expressions in a function so that I can start all the words in one sentence. Special Letter I know that I can do this: 

  word = ~ / ^ # {letter} /

to check that the word letter Begins with, but how do I talk to the word? Do I have to convert the string to an array and then have to walk through each word again, or is there a fast way to use regedx? I am using Ruby so that it will look:

<<> mailing_words = array.new sentance.split (""). Words | Match_words.push (word) if word = ~ / ^ # {letter} / end

Scan can be a good tool for this: 

  #! / Usr / bin / ruby1.8 s = "I think Paris is a beautiful place in the spring" p s.scan (/ \ b [this] [[:: alpha:]] * * / i) # = & gt; ; ["I", "think", "in", "the", "is"]
  • \ b means the word boundary . '
  • [: alpha:] means upper or lowercase alpha (az).

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime.

'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
