Python爬蟲入門（二）資料提取（lxml）

XPath文法和lXml子產品

什麼是XPath？

Xpath是一門在xml和html文檔中查找資訊的語言，可用來在xml和html文檔中對元素和屬性進行周遊

Xpath開發工具

1. chrome插件xpath helper
2. Firefox插件try xpath

Xpath文法：

選取節點：

XPath 使用路徑表達式在 XML 文檔中選取節點。節點是通過沿着路徑或者 step 來選取的。

謂語

謂語用來查找某個特定的節點或者包含某個指定的值的節點。

謂語被嵌在方括号中。

執行個體

在下面的表格中，我們列出了帶有謂語的一些路徑表達式，以及表達式的結果：

選取未知節點：

XPath 通配符可用來選取未知的 XML 元素。

一般使用方式

使用//擷取整個頁面當中的元素，然後寫标簽名，然後再填寫謂詞進行提取

需要主要的知識點

1./和//的差別：/代表隻擷取直接子節點。//擷取子孫結點。一般//

2.contains：有時候某個屬性包含多個值，可以使用contains

例如

//div[contains(@class,’jab-detail’)]
           

3.謂詞中的下标是從1開始的，不是從0開始的。

Lxml庫

Lxml是一個html/xml的解析器，主要功能是如何解析和提取html/xml資料

Lxml和正則一樣，也是用C實作的，是一款高性能的python html/xml解析器，我們可以利用之前學習的xpath文法，來快速的定位特定的元素以及結點資訊。

需要安裝C語言庫，可以使用pip安裝：pip install lxml

基本使用：

我們可以利用他解析html代碼，如果html代碼不規範，他會自動補全。

#encoding=utf-8

htmlElem=etree.HTML(text)
print(etree.tostring(htmlElem,encoding='utf-8').decode('utf-8'))
           

解析html檔案，預設使用的是xml解析器，所有如果遇到不規範的html代碼的時候會解析錯誤，這時候要自己解析HTML解析器。

除了直接從字元串進行解析，lxml還支援從檔案中讀取内容，建立一個hello.html檔案

然後利用etree.parse()方法進行讀取

htmlElme=etree.parse("hello.html)
           

當出現以下情況，網頁裡面标簽不比對

可以使用HTMLParser解析HTML代碼

parser=etree.HTMLParser(encoding='utf-8')
htmlElme=etree.parse("text.html",parser=parser)
           

執行個體代碼

from lxml import etree

parser=etree.HTMLParser(encoding='utf-8')
html=etree.parse("tenxun.html",parser=parser)

#取出所有的div标簽
# divs=html.xpath("//div")
# for div in divs:
#     print(etree.tostring(div,encoding='utf-8').decode('utf-8'))

#取出第二個div标簽
# div=html.xpath("//div[2]")[0]
# print(etree.tostring(div,encoding='utf-8').decode('utf-8'))

#擷取到class=header-wrap的div标簽
# divs=html.xpath("//div[@class='header-wrap']")
# for div in divs:
#     print(etree.tostring(div,encoding='utf-8').decode('utf-8'))

#擷取所有的a标簽的href屬性
# ass = html.xpath("//a/@href")
# for a in ass:
#     print("https://www.luogu.org/problem/list"+a)

#擷取純文字
trs=html.xpath("//div[@class='row-wrap']")
infos=[]
for tr in trs:
    #href傳回的是清單，不能直接寫出fullhref='https://www.luogu.org/problem/list'+href
    href=tr.xpath(".//div[@class='title']/a/@href")[0]
    fullhref='https://www.luogu.org/problem/list'+href
    num=tr.xpath(".//div[@class='part left-part']/span/text()")[0]
    title=tr.xpath(".//div[@class='title']/a/text()")[0]
    info={
        '題号':num,
        '名字':title
    }
    infos.append(info)
print(infos)
