extracting attributes from html with lxml

html, lxml, python

Solution

You are using lxml so you are operating with lxml objects - HtmlElement instances. HtmlElement is nested from etree.Element: http://lxml.de/api/lxml.etree._Element-class.html, it have get method, that returns attrubute value. So the proper way for you is:

from lxml import html 

...
tree = html.fromstring(page.text)
for link_element in tree.xpath('//div[contains(@class, "my_div")]//a'):
    href = link_element.get('href')
    image_element = href.find('img')
    if image_element:
        img_src = image_element.get('src')

Problem

I use `lxml` to retrieve the attributes of tags from an html page. The html page is formatted like this: ``` <div class="my_div"> <a href="/foobar"> <img src="my_img.png"> </a> </div> ``` The python script I use to retrieve the url inside the `<a>` tag and the `src` value of the `<img>` tag inside the same `<div>`, is this: ``` from lxml import html ... tree = html.fromstring(page.text) for element in tree.xpath('//div[contains(@class, "my_div")]//a'): href = element.xpath('/@href') src = element.xpath('//img/@src') ``` Why don't I get the strings?
