BeautifulSoup解析器
在我們使用BeautifulSoup的時候，選擇怎樣的解析器是至關重要的。使用不同的解析器有可能會出現不同的結果！
今天遇到一個坑，在解析某html的時候。使用html.parser解析器自己將table標簽截斷了（當然這與html本身有直接關系）
原html如下
<table cellpadding="0" cellspacing="0" style="WIDTH: 426.85pt; BORDER-COLLAPSE: collapse; MARGIN-LEFT: 0pt">
<tbody>
<tr>
<td style="BORDER-BOTTOM: #000000 0.75pt solid; BORDER-LEFT: #000000 0.75pt solid; PADDING-LEFT: 5.03pt; WIDTH: 24.55pt; PADDING-RIGHT: 5.03pt; VERTICAL-ALIGN: middle; BORDER-TOP: #000000 0.75pt solid; BORDER-RIGHT: #000000 0.75pt solid">

BeautifulSoup官方推薦使用lxml
推薦使用lxml作為解析器,因為效率更高. 在Python2.7.3之前的版本和Python3中3.2.2之前的版本,必須安裝lxml或html5lib, 因為那些Python版本的標准庫中內置的HTML解析方法不夠穩定.
提示: 如果一段HTML或XML文檔格式不正確的話,那么在不同的解析器中返回的結果可能是不一樣的,查看 解析器之間的區別 了解更多細節
