I'm scrapping data using lxml
This is the inspect element of single post
<article id="post-4855" class="post-4855 post type-post status-publish format-standard hentry category-uncategorized">
<header class="entry-header">
<h1 class="entry-title"><a href="http://aitplacements.com/uncategorized/cybage/" rel="bookmark">Cybage..</a></h1>
<div class="entry-meta">

<div class="entry-content">
<p>cybage placement details shared <a href="http://aitplacements.com/uncategorized/cybage/" class="read-more">READ MORE</a></p>
</div><!-- .entry-content -->
For every such post, I want to extract title, content of post, and post timing.
For example in above, the details will be
{title : "Cybage..",
post : "cybage placement details shared"
datetime="2017-09-13T11:02:32+00:00"
}
Till now what I'm able to achieve: the website requires login, I'm successfull in doing that.
For extracting information:
headers = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64)
Chrome/42.0.2311.90'}
url = 'http://aitplacements.com/news/'
page = requests.get(url,headers=headers)
doc = html.fromstring(page.content)
#print doc # it prints <Element html at 0x7f59c38d2260>
raw_title = doc.xpath('//h1[@class="entry-title"]/a/@href/text()')
print raw_title
The raw_title gives empty value []
?
What I'm doing wrong ?
@href
refers to the value of the href
attribute:
In [14]: doc.xpath('//h1[@class="entry-title"]/a/@href')
Out[14]: ['http://aitplacements.com/uncategorized/cybage/']
You want the text of the <a>
element instead:
In [16]: doc.xpath('//h1[@class="entry-title"]/a/text()')
Out[16]: ['Cybage..']
Therefore, use
raw_title = doc.xpath('//h1[@class="entry-title"]/a/text()')
if len(raw_title) > 0:
raw_title = raw_title[0]
else:
# handle the case of missing title
raise ValueError('Missing title')
