Ruby on rails HTTParty解析HTML,ruby-on-rails,html-parsing,httparty,Ruby On Rails,Html Parsing,Httparty,我正在寻找一种方法，从格式相当好但不太完美的xml网站中提取特定内容： <html> <head> <title>title</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <META HTTP-EQUIV="expires" CONTENT="now"> <meta h

我正在寻找一种方法，从格式相当好但不太完美的xml网站中提取特定内容：

<html>
  <head>
    <title>title</title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    <META HTTP-EQUIV="expires" CONTENT="now">
    <meta http-equiv=refresh content=300>
  </head>
<body bgcolor="#FFFFFF">
<p><font face="Arial, Helvetica, sans-serif" size="2"><img src="pict.gif" width="503" height="43"><br></font></p>
<p><font face="Arial, Helvetica, sans-serif" size="2">Please Note: ...<br></font></p>
<font face="Arial, Helvetica, sans-serif" size="3"><B>The Schedule</B></font><p></p>
<table border=0 width="100%">
  <tr> 
    <td><font face="Arial, Helvetica, sans-serif" size="2"><B>CONTENT A</B></font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td>
        <td><font face="Arial, Helvetica, sans-serif" size="2"><B>CONTENT B</B></font>&nbsp;&nbsp;</td>
        <td><font face="Arial, Helvetica, sans-serif" size="2"><B>CONTENT C</B></font>&nbsp;&nbsp;</td>
        <td><font face="Arial, Helvetica, sans-serif" size="2"><B>CONTENT D</B></font>&nbsp;&nbsp;</td>
    <td><font face="Arial, Helvetica, sans-serif" size="2"><B>CONTENT E</B></font></td>
  </tr>
...
但是xml不会解析，如果我切换到format:html，那么我似乎没有任何解析的优点。我在这里的想法很接近吗

谢谢，

我知道这是很久以前的事了，但我认为Nokogiri xpath解析会更好。我知道这是很久以前的事了，但我认为Nokogiri xpath解析会更好。
