Query xml in SQL Server - escaping square brackets -

i trying query xml in sql server getting errors due data contains [ , ].

my xml format (third party cannot change format , rid of square brackets):

<myrootelement>     <mychildelement name="[name1]"><mychildelement>     <mychildelement name="[name2]"><mychildelement>     <mychildelement name="[name3]"><mychildelement> </myrootelement> 

i want records xml contains mychildelement name.

i have tried:

select *  mytable myxmlcolumn.exist(n'/myrootelement/myrootelement[@name=[name2]]') = 1 

sql error message:

xquery invalid source character: [

if escape square brackets of [name](=[name1]), complains &

so how can make query work?

is there better way?

literal string should goes in double quotes, no escaping needed case :

select *  mytable myxmlcolumn.exist(n'/myrootelement/mychildelement[@name="[name2]"]') = 1
