使用C＃在文本文件中搜索模式

Question

I have multiple text files.I need value 'UA-8798837-1' (without the qoutes) from the code below. So steps will be-:

1. open the text file abc.txt .
2. search for a pattern starting from "_gaq.push".
3. If pattern matches I will skip a few characters "(['_setAccount', ".
4. select the key 'UA-8798837-1' (without quotes).
5. Save this key value in a variable called "key".

Text file's code -:

<script type="text/javascript">//<![CDATA[
    var _gaq = _gaq || [];
    _gaq.push(['_setAccount', 'UA-8798837-1']);
<script>

So basically I need to search for a pattern and if that is found I need to skip a few characters to select a code which is after the character " ' " and copy this value till the character " ' " is found again. Selection start at character " ' " 'UA-8798837-1' and ends at character " ' " value is UA-8798837-1. Please tell me how to do it .Thanks in advance.

Answer 1

This is a pretty simple regex:

/\\[\\'_setAccount\\', \\'(.+)\\'/

You can see what the matched groups will look like here.

And in case you haven't worked with regex in C# before, this is a good place to get started. Since you want to work with multiple matches, this link is probably even more relevant.

Answer 2

I think you are looking for this regex:

(?<=_gaq\.push\(\['_setAccount',\s')(.*)(?=')

If that will always be the case, you can use that regex to match the key that you are looking for .

But I will not give you the code for getting it in C# code, Please let me know what you tried. Thanks.

Hope it helps.
