I have string like this:

<?xml>
<some>
    <tag>
    </tag>
</some>
<data>
    Here replace ' with ''
</data>
</xml>

where I need to take only the contents within <?xml></xml> that is:

<some>
    <tag>
    </tag>
</some>
<data>
    Here replace ' with ''
</data>

I tried the regex: <?xml>.</xml> but that doesnt work.

Any help?
