trying to run the example sample code.

I just installed pdfquery in my machine, and I'm trying to run the example sample code:

import pdfquery
pdf = pdfquery.PDFQuery("examples/sample.pdf")
pdf.load()
label = pdf.pq(':contains("Your first name and initial")')
left_corner = float(label.attr('x0'))
bottom_corner = float(label.attr('y0'))
name = pdf.pq(':in_bbox("%s, %s, %s, %s")' % (left_corner, bottom_corner-30, left_corner+150, bottom_corner)).text()
print name

the problem is that I get this error

Traceback (most recent call last):
File "testePdfQuery.py", line 1, in
import pdfquery
File "/home/ubuntu/Downloads/pdfquery-0.1.3/pdfquery/init.py", line 1, in
from .pdfquery import PDFQuery
File "/home/ubuntu/Downloads/pdfquery-0.1.3/pdfquery/pdfquery.py", line 23, in
cssselect.Function._xpath_in_bbox = _xpath_in_bbox
AttributeError: 'module' object has no attribute 'Function'

any ideas how I can fix this and run the example? Thanks in advance.

Sorry - this is a known issue that has to do with incompatibility with recent versions of lxml. I just merged this pull request that catches the error ( #5 ), so try reinstalling pdfquery from github trunk and see if that fixes it.

This is a temporary fix that means you can't use xpath_in_bbox as described in the docs. It would be good to have a solution that keeps functionality with the new lxml -- this pull request might do it, but I haven't had time to play with it ( #3 ).

Hi, thanks for answering. How can I uninstall this version I installed? :) sorry, I'm a python newbie.

NVM, I got it with pip uninstall. I will try getting the code from github trunk and will get you notified if I can run the example. Thanks.

Welcome! First, if you haven't yet, you want to get pip working, the python
package manager. See http://www.pip-installer.org . Then (if you have git
installed) you should be able to do something like:

pip uninstall pdfquery
pip install -e git+https://github.com/jcushman/pdfquery.git#egg=pdfquery

This uninstalls the package and installs from source. As far as I know, all
this is doing behind the scenes is adding and removing files to your
site-packages directory (
http://stackoverflow.com/questions/122327/how-do-i-find-the-location-of-my-python-site-packages-directory
),
so in theory you could also do that directly.

(As you dig into python you might want to take a look at virtualenv, which
lets you keep a separate set of packages for each project you work on
instead of having them all jammed into site-packages. No need to complexify
it too much at this point though.)

Jcushman, I followed your instructions and I installed the pdfquery from the source code on github. Now I try to run the sample code and I get this:

Traceback (most recent call last):
File "testePdfQuery.py", line 3, in
pdf = pdfquery.PDFQuery("examples/sample.pdf")
NameError: name 'pdfquery' is not defined

I get this error even if I have the import in my file "import pdfquery".

print sys.path gives me this

Hmm, that one's tough to diagnose from here. pip I think would probably put
the files in /usr/lib/python2.7/dist-packages, so you would end up with
/usr/lib/python2.7/dist-packages/pdfquery/pdfquery.py and it would import
from there. If it installed as a .egg (really a zip file), you might try
unzipping it.

Er, /usr/ _local_ /lib/python2.7/dist-packages , I meant.

Right, I checked how pip installed it. It is installed as "pdfquery.egg-link". I've tried to unzip it, but no success :(

root@ubuntu-DQ77PRO:/usr/local/lib/python2.7/dist-packages# unzip pdfquery.egg-link

End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
