how to extract onclick in Hpricot ruby

i want to get the parentID from this. 

<div class="module-head" onclick="getURL('/DU/initAction.do?parentId=1063&categoryType=6')"></div>

how can i achieve this?

Solution

  • The setup:

    html = <<-EOF
<div class="module-head" onclick="getURL('/DU/initAction.do?parentId=1063&categoryType=6')"></div>
EOF

    Hpricot:

    doc = Hpricot html

    or Nokogiri:

    doc = Nokogiri::HTML html

    Interestingly, it's the same in both:

    doc.at('div')[:onclick][/parentId=(\d+)/, 1]
#=> "1063"
