python、lxml检索列表中的所有元素

我正在尝试从网站获取列表中的所有元素

从以下html代码段：

<ul>
    <li class="name"> James </li>
    <li> Male </li>
    <li> 5'8" </li>
</ul>

印刷品

[' James ', ' Male ', ' 5\'8" ']

---

XPath

“//li[../li[@class=“name”and position（）=1]]/text（）”

表示

//li             # all li elements
[                # whose
..               # parent
/                # has a child 
li               # li element
  [              # whose
   @class="name" # class attribute equals "name"
   and           # and 
   position()=1] # which is the first child element
  ]               
  /text()        # return the text of those elements 

[' James ', ' Male ', ' 5\'8" ']

//li             # all li elements
[                # whose
..               # parent
/                # has a child 
li               # li element
  [              # whose
   @class="name" # class attribute equals "name"
   and           # and 
   position()=1] # which is the first child element
  ]               
  /text()        # return the text of those elements 

from lxml import html

text = '''<ul>

tree = html.fromstring(text)
for ul in tree.xpath('//ul[li[@class="name"]]'):  # loop through the ul tag, whose child tag contains class attribute and the value is 'name'
    print(ul.xpath("li/text()")) # get all the text in the li tag

[' James ', ' Male ', ' 5\'8" ']
[' James ', ' Male ', ' 5\'8" ']
[' James ', ' Male ', ' 5\'8" ']
