Question

我正在尝试使用BeautifulSoup for python从网站解析html数据。但是，urllib2或mechanize无法读取整个html格式。返回的数据是

<html>
<head>
    <title>
    EC 4.1.2.13 - Fructose-bisphosphate aldolase    </title>
    <meta name="description" content="Information on EC 4.1.2.13 - Fructose-bisphosphate aldolase">
    <meta name="keywords" content="EC,Number,Enzyme,Pathway,Reaction,Organism,Substrate,Cofactor,Inhibitor,Compound,KM Value,KI Value,IC50 Value,pi Value,Turnover Number,pH,Temperature,Optimum,Range,Source Tissue,BLAST,Subunits,Modification,Crystallization,Stability,Purification">
</head>

        <frame name="flat" src="flat_result.php4?ecno=4.1.2.13&organism_list=Mycobacterium tuberculosis&Suchword=&UniProtAcc=P67475" frameborder="no">

    </frameset>
</frameset>
<noframes>
<body>
<h1>EC 4.1.2.13 - Fructose-bisphosphate aldolase </h1>

<a href="flat_result.php4?ecno=4.1.2.13&organism_list=Mycobacterium tuberculosis&Suchword=&UniProtAcc=P67475">More detailed information on the enzyme EC 4.1.2.13 - Fructose-bisphosphate aldolase</a>

Sorry, but your browser doesn't support frames. Please use another browser!

</html>

当我使用Internet Explorer手动打开webste时，可以读取整个html。无论如何使用urllib2，mechanize或BeautifulSoup来解决这个问题？

Answer 1

那是因为内容在框架中。您可以解析页面并查找主src元素的<frame>属性，也可以直接请求该帧。在大多数浏览器中，您可以右键单击并选择“框架属性”，以获取框架的URL。
