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

这是html_src

如果我尝试打印"target_value_list"，那么它会打印一些内存地址的列表。请有人救救我。

我想打印traget_value_list中的内容。想知道它是否html_src所有项目。

如果你想获取文本值列表而不是webelements列表，你可以尝试在XPath中使用/text()语法：例如，使用//div/text()或//div//text()，而不仅仅是//div或使用text属性或text_content()方法，如下所示：

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