check XML node exists or not using javascript -


how check 'roster' has no child values using javascript 

<club code="3rd1" tvcode="">    <name>3rd place team 1</name>    <roster/> </club> <club code="3rd1" tvcode="">    <name>3rd place team 1</name>    <roster>      <player code="auq"/>    </roster> </club>

if can use jquery,

you can parse using $.parsexml 

xmldoc = $.parsexml( "<xml></xml>" );

and can use find prefered node

$(xmldoc).find("roster")

and number of children via

.children().length

putting together

var rosterschildren = $(xmldoc).find("roster").children().length; console.log(rosterschildren > 0);

here sample fiddle.
