Transform symbol to element

Dear Friends,

This is possible to convert the quote symbol to xml elements?

If anybody know the way please share me, below placed my input file format
and required output format.
 
Input XML:

<p>This is the sample of double quote starting the double publication
ended</p>
<p>This is the sample of single quote starting the single publication
ended</p>


Output XML:

<para>This is the sample of double quote starting <quote open=""
close="">the double publication</quote> ended</para>
<para>This is the sample of single quote starting <quote open=""
close="">the single publication</quote> ended</para>

Advance in thanks,
Selva.
