Python和lxml.html按id获取元素输出问题

我目前正在尝试从html文件中获取数据。看起来我正在使用的代码工作正常，但并不像我预期的那样。我可以得到一些项目，但不是全部，我想知道这是否与我试图读取的文件的大小有关

我目前正在尝试解析的源代码

这一页有4500行，所以它的大小相当不错。我一直在使用这个页面，因为我想确保代码在大文件上工作

我使用的代码是：

import lxml.html
import lxml
import urllib2

webHTML = urllib2.urlopen('http://hobbyking.com/hobbyking/store/__39036__Turnigy_Multistar_2213_980Kv_14Pole_Multi_Rotor_Outrunner.html').read()
webHTML = lxml.html.fromstring(webHTML)
productDetails = webHTML.get_element_by_id('productDetails')
for element in productDetails:
    print element.text_content()

---

当我使用'mm3'或接近顶部的某个元素时，这会给出预期的输出，但如果我使用'productDetails'元素时，则不会得到任何输出。至少在我当前的设置中是这样。

恐怕

lxml.html

无法解析这个特定的html源代码。它将带有

id=“productDetails”

的

h3

标记解析为空元素（在a中）：

非常感谢你的帮助！我会继续尝试使用另一个答案。我没有意识到空元素是默认的恢复模式。我希望我读得更深一点，并且在花几个小时试图自己解决它之前知道这一点@当然可以，谢谢。仅供参考，我提到了

recover

模式只是为了指出

lxml.html

默认使用它，没有简单的方法可以告诉它更宽松。我完全理解。我只是没有在文档中看到这一点。这是一个巨大的帮助，因为我经常看到这个空元素，但无法理解它。
