After

Here is the HTML ...

     I am using nodejs I am trying to remove track id, in this case  11111111  the following  tracks% 2F . What is the most stable way to do this?  
 Should I use Regex or some JS string method such as  substring ()  or  match () ?   
  "itemprop =" text "> 
 after you try the node module [url + jsdom + qs]  
 this < / P> 
  var jsdom = need ('jsdom'); Var url = requirement ('url'); Var qs = is required ('qs'); On str = '& lt; IFrame width = "100%" height = "166" scroll = "no" frameborder = "no" '+' src = "http://w.soundcloud.com/player/?url=http% 3A% 2F% 2Fapi .soundcloud.com% 2Ftracks% 2F11111111 and auto_play = false "'+ & amp; Amp; Amp; Amp; Amp; Amp; Amp; Amp; Amp; Amp; Amp; Color = c3000d & amp; Show_comments = false & amp; Likes = + & Amp; Amp; Amp; Amp; Amp; Download = Incorrect & amp; Amp; Show_user = false & amp; Amp; Show_playcount = false; & Gt; & Lt; / Iframe & gt; '; Jsdom.env ({html: str, script: ['http: // code.jquery.com/jquery-1.5.min.js'], done: function (errors, window) {var $ = window; src = $. ('Iframe') (src '); Ares = attr.' Qs.parse (decodeurIComponent (url.parse (src) .query). Url.split ('/'); var track_id = aRes [ ARes.length-1]; console.log ("track_id =", track_id);}};    The result is:  
  track_id = 11111111

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,

I want to know if there is any method which can control the APK's building process or encoding at our source, there is no way to create APK with our source from our source, with a slight variation based on our SQF XML file. . Or any other way to create an APK file    When the app is running, I do not want to read my config file every time, I have to include a change in the application        If you want to manually create your application:    If you are developing in Eclipse, then the ADT plugin The enhanced project as you make changes to the source code.
