【已解决】Selenium中Python解析百度搜索结果第一页获取标题列表

折腾:
【未解决】Mac中用Selenium自动操作浏览器实现百度搜索
期间,已经用Selenium实现了百度首页的输入并搜索,显示出搜索结果了:
接下来,想办法实现,解析出搜索结果的标题的列表
此处尽量用多种方式去获取到最终结果,以演示如何写代码解析网页内容。
其中一种,和此处最相关的是,用Selenium自带的函数。

然后去:
【已解决】Selenium中如何实现百度搜索结果标题元素的定位
用Selenium的代码是:
# get search result item list
searchResultAList = chromeDriver.find_elements_by_xpath("//h3[contains(@class, 't')]/a")
print("searchResultAList=%s" % searchResultAList)
for curIdx, curSearchResultAElem in enumerate(searchResultAList):
  print("%s [%d] %s" % ("-"*20, curIdx, "-"*20))
  aHref = curSearchResultAElem.get_attribute("href")
  print("aHref=%s" % aHref)
  aText = curSearchResultAElem.text
  print("aText=%s" % aText)
输出:

  • get_attribute(name)
  • get_property(name)
回头都试试
其中可见,对于,从复杂的html代码解析出所需要的值,往往比较费精力
对此,其实Python中有更专业的库干这个:BeautifulSoup
接着去想办法看看,能否获取Selenium的当前页面的html,然后在用BeautifulSoup去解析获取所需的值
那去搞清楚:
【已解决】Selenium中如何获取到当前页面的html源码
然后去写代码:
# Method 2: use BeautifulSoup to extract title list
curHtml = chromeDriver.page_source
curSoup = BeautifulSoup(curHtml, 'html.parser')
beginTP = re.compile("^t.*")
searchResultH3List = curSoup.find_all("h3", {"class": beginTP})
print("searchResultH3List=%s" % searchResultH3List)
经过调试,是可以找到H3的元素的:
继续调试:
for curIdx, searchResultH3Item in enumerate(searchResultH3List):
  print("%s [%d] %s" % ("-"*20, curIdx, "-"*20))
  aElem = searchResultH3Item.find("a")
  print("aElem=%s" % aElem)
  baiduLinkUrl = aElem.attrs["href"]
  print("baiduLinkUrl=%s" % baiduLinkUrl)
  title = aElem.text
  print("title=%s" % title)
是可以的:
【总结】
至此,用BeautifulSoup的代码去解析出百度搜索结果的列表:
# Method 2: use BeautifulSoup to extract title list
curHtml = chromeDriver.page_source
curSoup = BeautifulSoup(curHtml, 'html.parser')
beginTP = re.compile("^t.*")
searchResultH3List = curSoup.find_all("h3", {"class": beginTP})
print("searchResultH3List=%s" % searchResultH3List)
for curIdx, searchResultH3Item in enumerate(searchResultH3List):
  print("%s [%d] %s" % ("-"*20, curIdx, "-"*20))
  aElem = searchResultH3Item.find("a")
  # print("aElem=%s" % aElem)
  baiduLinkUrl = aElem.attrs["href"]
  print("baiduLinkUrl=%s" % baiduLinkUrl)
  title = aElem.text
  print("title=%s" % title)
