python解析html提取数据,并生成word文档

html转word AI君 24℃

今天试着用ptyhon做了一个抓取网页内容,并生成word文档的功能,功能很简单,做一下记录以备以后用到。

生成word用到了第三方组件python-docx,所以先进行第三方组件的安装。由于windows下安装的python默认不带setuptools这个模块,所以要先安装setuptools这个模块:

1、在python官网上找到 https://bootstrap.pypa.io/ez_setup.py  ,把代码保存到本地并执行:  python ez_setup.py

2、下载python-docx  (https://pypi.python.org/pypi/python-docx/0.7.4),下载完成后解压并进入到  XXX\python-docx-0.7.4 安装python-docx : python setup.py install

这样python-docx就安装成功了,可以用它来操作word文档了,word文档的生成参考的这里https://python-docx.readthedocs.org/en/latest/index.html

html解析用到的是sgmllib里的SGMLParser  url内容的获取用到的是urllib、urllib2

代码如下:

# -*- coding: cp936 -*-
from sgmllib import SGMLParser
import os
import sys
import urllib
import urllib2
from docx import Document
from docx.shared import Inches
import time

##获取要解析的url
class GetUrl(SGMLParser):
    def __init__(self):
        SGMLParser.__init__(self)
        self.start=False
        self.urlArr=[]


    def start_div(self,attr):
        for name,value in attr:
            if value=="ChairmanCont Bureau":#页面js中的固定值
                self.start=True


    def end_div(self):
        self.start=False


    def start_a(self,attr):
        if self.start:
            for name,value in attr:
                self.urlArr.append(value)
            


    def getUrlArr(self):
        return self.urlArr
    
##解析上面获取的url,获取有用数据
class getManInfo(SGMLParser):
    def __init__(self):
        SGMLParser.__init__(self)
        self.start=False
        self.p=False
        self.dl=False
        self.manInfo=[]
        self.subInfo=[]

    def start_div(self,attr):
        for name,value in attr:
            if value=="SpeakerInfo":#页面js中的固定值
                self.start=True

    def end_div(self):
        self.start=False

    def start_p(self,attr):
        if self.dl:
            self.p=True

    def end_p(self):
        self.p=False

    def start_img(self,attr):
        if self.dl:
            for name,value in attr:
                self.subInfo.append(value)
        


    def handle_data(self,data):
        if self.p:
            self.subInfo.append(data.decode('utf-8'))


    def start_dl(self,attr):
        if self.start:
            self.dl=True

    def end_dl(self):
        self.manInfo.append(self.subInfo)
        self.subInfo=[]
        self.dl=False

    def getManInfo(self):
        return self.manInfo
