Parse XML with hpricot, get attributes -

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।

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

-
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
