如何打印xpath解析器

Question

我在解析Python 2.7/Flask 0.12中的lxml时遇到了一些麻烦。

我想打印解析的xpath数据，但找不到一种方法。 这是我的代码。

from lxml import html 
from lxml import etree 

def parse_html(html_src): 
    target_xpath = //div[@class="primary-content"]//div[@class="mini-cart-product clearfix"]' 

    detail_html = html.fromstring(html_src) 
    page_tree = etree.ElementTree(detail_html) 

    target_value_list = page_tree.xpath(target_xpath) 
    #want to print 'target_value_list' 

    return target_value_list 

这里的html_src

<div class="mini-cart-product clearfix">

如果我尝试打印 'target_value_list'，然后它打印一些内存地址的列表。 请有人救我。

我想打印什么是traget_value_list。想知道它是否包含html_src中的所有项目。

如果你想要得到的文本值，而不是webelements的名单列表，你可以尝试使用/text()语法XPath：使用，例如，//div/text()或//div//text()而不是仅仅//div或使用text财产或低于text_content()方法：

target_value_list = [element.text_content() for element in page_tree.xpath(target_xpath)] 
return target_value_list
