Reading xpath value error - Lxml

[bubufff]

Hi all, 

I am trying to crawl the information from this link 

http://muaban.net/mua-ban-nha-quan-thu-duc-l5924-c32/quan-thu-duc-ban-nha1lau-2mt-truoc-sau-dg-ng-cong-tru-p-hiep-phu-q9-dt-4x21-5m--id15946781

and this is the code I use

link = 
> "http://muaban.net/mua-ban-nha-quan-thu-duc-l5924-c32/quan-thu-duc-ban-nha1lau-2mt-truoc-sau-dg-ng-cong-tru-p-hiep-phu-q9-dt-4x21-5m--id15946781;
> xPath =  "id('pC_DV_tableHeader')/x:tbody/x:tr[4]/x:td[3]"
> namespace = {'x': 'http://www.w3.org/1999/xhtml'}
>
> tree = lxml.html.parse(link)
> arrayContent = tree.xpath(xPath + "/text()", namespaces=namespace)
>
> if len(arrayContent):
>  content = cgi.escape(arrayContent[0].encode("utf-8"))
>

I use xPath checker add-on of firefox to read the xPath value and the 
namespace. However, when running the code, I always get the content empty. 
How can I solve this ?

Re: Circular import problem

Thank all, I just moved the import to the local function and it works. 
Still re-factoring the codes to overcome this issue completely

Circular import problem

[bubufff]

Hi all,

I have a util file, which will do some stuffs and then, update a model (so 
i have to import the models in this file). Also, in my models file, I 
trigger a post_save signal to call the util file file (so I have to import 
this file in the models file). Obviously, I will get a circle import 
problem. Therefore, what is the best practices in this situation ?
