my regex is (\[((?!attr1)[^\]])*\]) and want to make it a compiled template and pass the "attr1" part dynamically.

input string root/element1/element2[@attr1='abc']/element3[attr2='xyz']/element4/element5[attr3='pqr']/element6/element7

Want to pass the attr1, attr2, attr3 dynamically to the regex template and trying to work with one regex object for performance reasons. can you please help me?

attr values are dynamic values and can be anything – user845392 May 12 '17 at 03:55

Why not construct your Regex string dynamically? `string reg = string.Format(@"(\[((?!{0})[^\]])*\])", aatr1);` – FortyTwo May 12 '17 at 04:18
