Xpath php: get attribute value start with

Question

I would like to extract in an html page all the attribute names that start with ctl00$ctl00$mainContent$bodyContent$chkRitira_ and check if the input tag is checked. For example I have this piece of html code:

                 <tr>
                    <td operazione="ritira"><input id="ctl00_ctl00_mainContent_bodyContent_chkRitira_852428" type="checkbox" name="ctl00$ctl00$mainContent$bodyContent$chkRitira_852428" /><label for="ctl00_ctl00_mainContent_bodyContent_chkRitira_852428">Ritira</label></td>
                    </tr>                   
                <tr>
                    <td operazione="ritira"><input id="ctl00_ctl00_mainContent_bodyContent_chkRitira_852429" type="checkbox" name="ctl00$ctl00$mainContent$bodyContent$chkRitira_852429" /><label for="ctl00_ctl00_mainContent_bodyContent_chkRitira_852429"> Ritira</label></td>
                   </tr>

I want to check if every input check that starts with ctl00$ctl00$mainContent$bodyContent$chkRitira_ is checked and the name of the attribute, then:

ctl00$ctl00$mainContent$bodyContent$chkRitira_852428
ctl00$ctl00$mainContent$bodyContent$chkRitira_852429

I tried with:

 $xpR=new DOMXPath( $dom_richieste_r );
 $colR = $xpR->query( '//input[@name="ctl00$ctl00$mainContent$bodyContent$chkRitira_"]' );

But this gives me back the content of the node.

There is a starts-with that you can implement as below

//input[starts-with(@id, "ctl00$ctl00$mainContent$bodyContent$chkRitira_")]/@name
