问题 How would you read an XML file using sax and convert it to a lxml etree.iterparse element? To provide an overview of the problem, I have built an XML ingestion tool using lxml for an XML feed that will range in the size of 25 - 500MB that needs ingestion on a bi-daily basis, but needs to perform a one time ingestion of a file that is 60 - 100GB's. I had chosen to use lxml based on the specifications that detailed a node would not exceed 4 -8 GB's in size which I thought would allow the node

使用XPath

Xpath全称XML Path Language,即XML路径语言,它是一门在XML文档中查找信息的语言,它最初是用来搜索XML文档的,但是它同样适用于HTML文档的搜索 一.XPth概览 XPth提供了非常简洁明了的路径选择表达式,还提供了超过100个内建函数,用于字符串,数值,时间的匹配以及节点,序列的处理等。 二.XPath常用规则 XPath常用规则 表 达 式 描 述 nodename 选取此节点的所有子节点 / 从当前节点选取直接子节点 // 从当前节点选取子孙节点 . 选取当前节点 .. 选取当前节点的父节点 @ 选取属性 例如://title[@lang='eng'],这就是一个XPath规则,它代表选择所有名称为title ,同时属性lang的值为eng的节点 三.实例引入 from lxml import etree text=''' <div> <ul> <li class="item-0"><a href="link1.html">first item</a></li> <li class ="item-1"><a href="link2.html">second item</a></li> <li class ="item-inactive"><a href="link3.html">third item</a></li> <li class ="item

python简单应用!用爬虫来采集天猫所有优惠券信息,写入本地文件

今天给大家分享一个小网站的数据采集,并写到excel里面! 分析网站 目标网站是“小咪购”,这里有天猫所有的含有购物券的商品信息,我们今天就来抓它吧! 随便找一段文字,然后点击右键查看网页源代码,看看是否存在该文字,如果存在,那么这个网页就是静态网站了!很幸运,这个网站居然是静态的。 那就简单了,不需要去分析ajax加载数据或者找json包了,直接获取网页源代码==>>匹配相关内容==>>保存数据即可! 工具和库 Windows+python3.6 import random import time import requests from lxml import etree import xlwt 用这几个库就可以搞定了!注意xlwt和xlrd这2个库都是操作excel的,一个是保存数据,一个是读取数据,不要搞混了。 开始写代码 首先写一个函数,将所有的爬虫工作写到函数里,如下图 这个网站需要写上headers,不写是抓不到数据的!新建一个列表,将爬到的相关数据写入列表,它的形式大概是这样的:【【产品信息A1,2,3……】,【产品信息B1,2,3……】……】,这么写列表是因为我们最后要将他们写如excel表格,那么列表中的每一个元素(还是列表形式)都是一行数据,方便写入! 注意第33行,列表构成的时候,用+连接会将所有列表中的元素放入一个列表,比如:【1,2,3】+【4,5】=

Installing lxml, libxml2, libxslt on Windows 8.1

问题 After additional exploration, I found a solution to installing lxml with pip and wheel. Additional comments on approach welcomed. I'm finding the existing Python documentation for Linux distributions excellent. For Windows... not so much. I've configured my Linux system fine but I need some help getting a Windows 8.1 tablet ready as well. My project requires the lxml module for Python 3.4. I've found many tutorials on how to install lxml but each has failed. https://docs.python.org/3
