I have a file like this. `abc.txt`

```
<ra><r>12.34</r><e>235</e><a>34.908</a><r>23</r><a>234.09</a><p>234</p><a>23</a></ra>
<hello>sadfaf</hello>
<hi>hiisadf</hi>
<ra><s>asdf</s><qw>345</qw><a>345</a><po>234</po><a>345</a></ra>

```

What I have to do is I have to find `<ra>` tag and for inside `<ra>` tag there is `<a>` tag whose valeus I have to store the values inside of into some variables which I need to process further. How should I do this.?

values inside tag within tag are:  

`34.908,234.09,23`  

`345,345`
