Regular expression to match exact same block

Question

Please help me to find out a specific text included block from this file. I'm reading context using Node js fs.

<VirtualHost *:80> 
DocumentRoot /home/site1 
ServerName www.site1.com 
</VirtualHost>
<VirtualHost *:80> 
DocumentRoot /home/site2 
ServerName www.site2.com 
</VirtualHost>
<VirtualHost *:80> 
DocumentRoot /home/site3 
ServerName www.site3.com 
</VirtualHost>

Code:

fileContext.toString().split("\n");
 var matched = fileContext.toString().replace( /<VirtualHost[\s\S]*?<\/VirtualHost>/gm,"--matched--" );

above code is working fine but it will match all vhost blocks. I only needs to find vhost block which is contain "www.site2.com"

Answer 1

After some deliberation, I've come to the conclusion that regex isn't going to cut the mustard. I'd recommend using node-apacheconf .

var name = "www.site2.com";

apacheconf('/etc/apache2/httpd.conf', function(err, config, parser) {
  if (err) throw err

  console.log(config.VirtualHost.filter(function(vh) {
    return vh.ServerName == name;
  }));
});
