I think this is what you need:
Code:
$ cat file.xml
 <Head="Test"  Id="3" >
            <Title="mode" >

Code:
$ cat temp.sh
Head=`grep Head file.xml | sed 's/.*Head="\([^"]*\)".*/Head=\1'/`
Title=`grep Title file.xml | sed 's/.*Title="\([^"]*\)".*/Title=\1'/`
echo $Head
echo $Title

Code:
$ ./temp.sh
Head=Test
Title=mode

-------------------------

Another way to get rid of the "" characters, using your existing code, would be to add to the end of your pipeline:
Code:
tr -d '"'
