Java Parse XML file in shell script

Hi Everybody,

I have an XML file containing some data and i want to extract it, but the specific issue in my file is that the data is repeated some times like the following example :

<section1>
<subsection1>
X=...
Y=...
Z=...
<\subsection1>
<subsection2>
X=...
Y=...
Z=...
<\subsection2>
<\section1>

the idea is to select (or extract) X and Z for a specific subsection only, note here that the number of subsection is changing frequently, (grep didn't work).

Many thanks in advance for your help.
