xml - Python xpath not working? -

-

OK, this is starting to drive me a little bit crazy I have used several XML / Xpath libraries for Python Have tried, and can not find an easy way to get a stinkin '' title 'element'.

The latest attempt looks like this (using Amara): 

  def view (req, url) for node in

But this Does not print. My XML looks like this:

If I try to // title instead of //, then it gives everything as expected I know that XML has title , so what's the problem? Is this a name or something? If so, how can I fix it?

This does not work with any prefix, but it works: 

  def view (req, url): req.content_type = 'Text / plain' doc = amara.parse (url, prefix = {'atom': 'http://www.w3.org/2005/Atom'}) req.write (str (Doc.xml_xpath ('// Atom: title '))

You probably just focus on the name space of that document Which you want to deal with.

I see how to deal with namespace in Amara:

Edit: I did not make any edits using my code snippet Find out which Amara you are using, but depending on the docs I tried to adjust it as much as possible: 

  def view (req, url): req.content_type = 'Text / plain' NS = {u'f ': u'http: //www.w3.org/2005/ atom', u't ': u' http: //purl.org/syndication/thread/1.0 '} Doc = amara.parse (urlopen (url), prefix = ns) req.write (str (doc.xml_ Xpath (u'f: title ')))

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne

c# - How can I find out if there are windows above a control? -

-
If I have Winforms controls, can it be possible to tell whether the window above it (from any application)? Actually, I have to know that some parts of my control are actually appearing on the screen. If you are happy to p / call, the EnumWindows function provides all top-level windows HWND on the screen is; This allows you to get a Non-Client Rectangle (GetWindowRect) to compare the limits of your form. This non-rectangular opaque areas (media player and fancy skins for choice), so you can be false positive for such a control window.

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
