Find/Replace Mulitple text files

Can someone help me with creating a script for the following
scenario...

search through multiple files with text:

-------------------------------------------------------
 texttexttexttexttexttexttexttexttexttext
texttext
 texttexttexttexttexttexttexttexttexttext
texttext
thedir="hello"
 texttexttexttexttexttexttexttexttexttext
texttext
 texttexttexttexttexttexttexttexttexttext
texttext
-------------------------------------------------------

find in each file the string: thedir="hello"
hold anything between the quotes in a buffer: hello
replace the string with a new string + buffer + string:
thedir="\hello\"

Thank you for any help.
