lxml에서 텍스트 가져 오기 Comment

Question

_Comment의 내용을 가져 오려고합니다. 나는 그것을 어떻게하는지에 대해 상당히 연구했지만, 텍스트를 얻기 위해 td 엘리먼트에서 함수에 접근하는 방법을 모른다. 도움이된다면 xpaths를 Python Scrapy 모듈과 함께 사용하고 있습니다.

td = None [_Element] 
    <built-in function Comment> = None [_Comment] 
    a = None [_Element] 

td 요소의 HTML은 다음과 같습니다

<table class="crIFrameReviewList"> 

    <tr> 
     <td> 

<!-- BOUNDARY --> 
<a name="R2L4AFEICL8GG6"></a><br />

     </div> 

For the recent few years Canon has made great efforts to improve their travel-zoom compact cameras, and the new SX700 is their next remarkable achievement on that way. It's a little bit bigger than its predecessor (SX280) but it is very well built and has an attractive look and feel (I like the black one). It also got a new front grip which makes one-hand shooting more convenient, even when shooting video, since the Video button was moved from the back to the top and you can now use your thumb solely for holding the camera.<br /><br />Here is a brief list of the new camera pros & cons:<br /><br />PROS:<br />* A very good design and build quality with the attractive finish.<br />* A new powerful 30x optical zoom lens in just a pocket-size body.<br />* Incredible range from 25mm wide to 750mm telephoto for stills and video.<br />* Zoom Framing Assist - very useful new feature to compose your pictures at long telephoto.<br />* Very effective optical Intelligent Image Stabilization for...

54,000 RPM - It has a spinning disk drive that is way beyond our time...I bought 10 of these just for the hard drive, they blow SSD's out of the water. 
Seriously though... how does a well known computer company mistype an important spec?
