    मैं HTML को अलग करने की कोशिश कर रहा हूं एचटीएमएल-कोड से टैग नाम मेरा HTML- कोड इस प्रकार है: 

      & lt; div id = "MyDiv" शैली = "बाएं: 100px; शीर्ष: 10px;" & Gt; Div & lt; strong & gt; में कुछ पाठ & LT; उन्हें & gt; एएम के लिए कुछ पाठ & lt; p & gt; & lt; b & gt; बी, & lt; span id = "MySpan" & gt; span1,   
     रीग-एक्स को कॉल करने के बाद मुझे उम्मीद है कि सभी मान्य HTML-Tagname स्ट्रिंग से जैसे एचटीएमएल-कोड से ऊपर से कुछ का परिणाम निम्नानुसार होगा: div, strong, em, p, b, span। यह मेरा दृष्टिकोण है:  
      sTagName = sTagName.replace (/ & lt; * (। *) * & Gt; /, '$ 1'); चेतावनी (sTagName);   
     उपरोक्त RegEx- स्टेटमेंट  & lt; div & gt;  परिणाम:  div  यह ठीक है। लेकिन यह  & lt; Div stlye = "..." & gt;  परिणाम:  div stlye = "..."  यह गलत है मैं इसके लिए केवल एक  div  की अपेक्षा करता हूं दूसरे शब्दों में HTML-Tagname में स्थान के बाद स्ट्रिंग को हटा दिया जाना चाहिए, ताकि मुझे div-Tagname मिले। प्रदर्शन के कारणों के लिए मैं RegEx- स्टेटमेंट को दो बार कॉल नहीं करूंगा अग्रिम धन्यवाद।   
     
     
     डोम के माध्यम से;  
      var el = $ ("& Lt; div / & gt;")। जोड़ें (html_string) .find ("*")। प्रत्येक (फ़ंक्शन () {चेतावनी ($ (यह) .प्रॉप ("टैगनाम"));};

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
