Body
I'm new to Python and trying to build one of my first webscrapers. I want to go to a page, open a bunch of subpages, find a specific link on the page (with an ID), and then I want to print the link-data. Right now I get the error: 'list indices must be integers, not str', which means I'm doing someting wrong in (atleast) the last line of code. What I'm really unsure about, is what I need to do to grab and parse the href data from a specific link - because I think, the rest is working (loading subpages). The scraper is (supposed) to grab all the urls of the Danish communes and print them, so the first line of print should be: <a href="http://www.albertslund.dk" rel="nofollow">http://www.albertslund.dk</a> (follow by 97 more) Anyway, here's the code - hope anyone can tell me, what I'm doing wrong. Thanks a bunch in advance. <pre><code>from BeautifulSoup import BeautifulSoup from mechanize import Browser f = open("kommuneadresser.txt", "w") br = Browser() url = "https://bdkv2.borger.dk/foa/Sider/default.aspx?fk=22&foaid=11541520" page = br.open(url) html = page.read() soup = BeautifulSoup(html) link = soup.findAll('a') kommunelink = link[21:116] #we create a loop - for every single kommunelink in the list, #'something' will happen for kommune in kommunelink: #the link-part is saved as a string kommuneurl = kommune['href'] #we construct a new url from two strings fuldurl = "https://bdkv2.borger.dk/" + kommuneurl #we open the page and save it in a variable kommuneside = br.open(fuldurl) #we read the page html2 = kommuneside.read() #we handle the page in beautifulsoup soup2 = BeautifulSoup(html2) #we find a specific link on the page hjemmesidelink = soup2.findAll('a', attras={'ID':"uscAncHomesite"}) print hjemmesidelink['href'] </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
