Python如何使用xpath解析

1、在命令行安装xpath包pip install lxml

3、在IDLE新建‘textxpath.py’文件，并写内容如下：from lxml 坡纠课柩import etreesx = 媪青怍牙''' <root> <h1>title</h1> <div> fd <img src="1.jpg"></img> </div> </root>'''exml = etree.XML(sx)x = exml.find('.//div')print (x.text)

5、修改代码使用绝对路径查找，代码如下：from lxml import etreesx = ''' <root> <h1>title</h1> <div> fd <img src="1.jpg"></img> </div> </root>'''exml = etree.XML(sx)x = exml.xpath('//div')print (x[0].text)

7、查找标签属性内容可以使用from lxml import etreesx = ''' <root> <h1>title</h1> <div> fd <img src="1.jpg">dd</img> </div> </root>'''exml = etree.XML(sx)x = exml.xpath('//img/@src')print (x)
