xwiki - cannot get "\"while reading an xml file -

i'm trying read xml page of xwiki line line when read line:

[[3.2.2>>doc:3\.2\.2]] 

it returns just

[[3.2.2>>doc:3.2.2]] 

any ideas why ignores \ .

so have xwiki page localpäge.xml :

<?xml version="1.0" encoding="utf-8" standalone="yes"?><page xmlns="http://www.xwiki.org"><content> ====[[projects>>webhome]]/[[scv>>scv]]/composant1====  |=release|=date  |[[3.3.3>>doc:3\.3\.3]]|2015-06-25:14:23:20 </content> </page> 

what i'm doing

while read echo "$i">>pagetosend.xml done < localpage.xml 

in pagetosend.xml instead of having

|[[3.3.3>>doc:3\.3\.3]]|2015-06-25:14:23:20  

i have

|[[3.3.3>>doc:=3.3.3]]|2015-06-25:14:23:20  

and want keep famous "\" .
