मेरा एक्सएमएल: 

  & lt; पूर्वानुमान_विवरण & gt; & Lt; शहर डेटा = "चेल्याबिंस्क, चेल्याबिंस्क प्रांत" / & gt; & Lt; / forecast_information & gt;

उदाहरण के लिए शहर का डेटा कैसे प्राप्त करें? अंदरूनी html नहीं, सिर्फ शहर के डेटा, डाक कोड आदि की विशेषताएँ

एक्सएमएल को पार्स करने में बड़ी मदद होगी । ऐसा लगता है, तो यह अविश्वसनीय रूप से आसान है।

डेटा तत्व के अंदर डेटा विशेषता को निकालने के लिए XPath अभिव्यक्ति निम्नानुसार है:

< Pre> / forecast_information / city / @ डेटा

अभिव्यक्ति कहता है, विशेषता डेटा नामित है (यह है कि @ साइन इन का मतलब है कि शहर नाम के तत्व के अंदर, जो कि forecast_information नाम के तत्व के अंदर है।

अब, XML आपको Google पर लिंक किया गया है आरयू आप यहां पोस्ट किए गए उदाहरण से अधिक जटिल है। इसके बारे में समान जानकारी निकालने के लिए, इस अभिव्यक्ति का उपयोग करें: 

  // city / @ data   
 यह अभिव्यक्ति कहती है, विशेषता   शहर  नामित तत्व के अंदर डेटा , स्रोत XML में  शहर  कोई बात नहीं है।

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...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
