grab the big-ones (img)

[schuster]

hi,
little prob to fetch the real pictures from the feeds
to fetch the thumbnails is not the goal i think.
can i fetch the big ones?

here are the links from inside html:

the thumbnail

the real (big) pic

i think i have to say "follow link" on img/scr , but how?

Use preprocess_html() and change the links.

<a href="/polopoly_fs/1.248951.1297710265!/httpImage/16361081.jpg_gen/derivatives/rpoPanorama_786/16361081.jpg" class="lightbox" rel="lightbox" title="Erster Gast auf dem Blauen Sofa in Grevenbroich: Bürgermeisterin Ursula Kwasny. Foto: Michael Reuter">

<script type="text/javascript" src="http://www.ngz-online.de:80/js/lightbox.js" language="JavaScript"/>

i had only to change this string
rpo54_195
with this one
rpoPanorama_786

[kovidgoyal]

for img in soup.findAll('img', src=True):
   img['src'] = img['src'].replace('rpo54_195', 'rpoPanorama_786')

[schuster]

o.k. that is next step, the string are changed

and now i got this:

Referenced file '/polopoly_fs/1.1255129.1305794277%21/httpImage/2533432514.jpg_gen/derivatives/rpoPanorama_786/2533432514.jpg' not found

[kovidgoyal]

Make the URL absolute.

[schuster]

o.k. that is tooooo difficult for me at beginner.
i want to read books to learn it.

is this the right way to make it absolut:

soup = BeautifulSoup()
tag1 = Tag(soup, "mytag")
tag2 = Tag(soup, "myOtherTag")

[kovidgoyal]

I just meant add the http://servername part to the links.

img['src'] = 'http://servername-whatever/' + img['src'].replace('xx', 'yy')

[schuster]

ah o.k. ,

i understand now!

but it show's like that the target picture is in a script-container also.

i believe , this is much more difficult.

i let it be and make a bit more simpler stuff.

thank you for assistance.

greetings
