I am getting like "No elements found found

When that happens, dump the innerHTML of body and verify the lack of such an element

print $body =~ m{(<li.*?class="next".*?</li>)};

Using firebug, if I turn off javascript, there is no search results, no next button

But if I turn on javascript,  $x('//li[@class="next"]'); returns two nodes

/html/body/form/div[2]/div[2]/div[2]/div/table/tbody/tr/td[2]/div/tabl
+e/tbody/tr[2]/td/span/div/ul/li[5]
/html/body/form/div[2]/div[2]/div[2]/div/table/tbody/tr/td[2]/div/tabl
+e/tbody/tr[25]/td/span/div/ul/li[5]

Also, maybe the search results are still loading
