我需要使用Rails和Nokogiri解析HTML.这是HTML:
<body>
<div id="mama">
<div class="test1">text</div>
<div class="test2">text2</div>
</div>
<div id="mama">
<div class="test1">text</div>
<div class="test2">text2</div>
</div>
<div id="mama">
<div class="test1">text</div>
<div class="test2">text2</div>
</div>
</body>
我应该如何形成循环问题？我已经尝试了很多次,但仍然收到错误或结果不好......
doc.xpath('//div[@id='mama']/?or what?').each do |node|
parse_file.puts text1
parse_file.puts text2
parse_file.puts text1
parse_file.puts \n
end
结果应该是这样的
text from first mama
text2 from first mama
text from first mama
text from second mama
and so on...
