regex - Find and replace to remove the icon in all my forms -

i'm using visual studio, , remove icon in forms on code. icon embedded in resx files, used following regular expression find icon, used find , replace:

\<data name=\"\$this\.icon\".+\n(.*\n)*^.+ree=\n(.*\n)(.*\n) 

the icon present in resx files following code:

      <data name="$this.icon" type="system.drawing.icon, system.drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">         <value>            aaabaagaicaqaaeabadoagaahgaaabaqeaabaaqakaeaag4daaawmaaaaqaiakgoaacwbaaaicaaaaea            ...            regaaaxbgagsqyabrehaaaxbwaosqeahrehgh6xb+d+sqf//ree=         </value>       </data> 

it works, performance bad. please, find faster regular expression?

thanks in advance.

this expression will:

• find data tags have attribute of name=$this.icon
• avoid of sticky problems using regex reading non regular markup languages

<data\b(?=\s)(?=(?:[^>=]|='[^']*'|="[^"]*"|=[^'"][^\s>]*)*?\sname="\$this\.icon")(?:[^>=]|='[^']*'|="[^"]*"|=[^'"\s]*)*"\s?\/?>(?:(?!<\/data>)[\s\s])*?<\/data>

sample text

note first data tag has difficult edge cases

<data onmouseover=' name="$this.icon" ; funreplace("</data>", name) ; ' type="system.drawing.icon, system.drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">         <value>            aaabaagaicaqaaeabadoagaahgaaabaqeaabaaqakaeaag4daaawmaaaaqaiakgoaacwbaaaicaaaaea            ...            regaaaxbgagsqyabrehaaaxbwaosqeahrehgh6xb+d+sqf//ree=         </value>       </data> <data name="$this.icon" type="system.drawing.icon, system.drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">         <value>            aaabaagaicaqaaeabadoagaahgaaabaqeaabaaqakaeaag4daaawmaaaaqaiakgoaacwbaaaicaaaaea            ...            regaaaxbgagsqyabrehaaaxbwaosqeahrehgh6xb+d+sqf//ree=         </value>       </data>
