If Statement in jQuery XML Ajax

[Jeje93]

Can I add an IF statement to a XML query with jQuery?My query is as follows.\[code\]$("#page_all").live('pagebeforecreate', function() { $.get('http://ontariosheep.org/mobile/data/data_all.php',function(data){ $('.content').empty(); $(data).find('market').each(function(){ var $market = $(this); html += '<div class="ui-block-a">' + $market.find('lambs').attr('head') + '</div>'; }}\[/code\]I'd like to add an if statement on line 6. So that 'html+=' only happens if "$market.find('lambs').attr('head')" is set.Is this possible, if so how?EDIT:All entries do have a head attribute BUT the ones without any head are blank like so head=""
