javascript - JQuery problem with html() handling in Opera -

-

I have followed the JS code (stripped at the minimum size where the problem still exists)

< Pre> & lt; Html & gt; & Lt; Top & gt; & Lt; Script type = "text / javascript" src = "jquery.js" & gt; & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Div id = "debug" & gt; This is & lt; Em> Trial & lt; / Em> & Lt; / Div & gt; & Lt; Script type = "text / javascript" & gt; Var string1 = $ ('# debug'). Html (); Var string 2 = string 1 Location (/ em & gt; / g, ' gt;'); String 2 = String 2.Rail (/ / g, ''); $ ('# Debug'). Html (string 2); & Lt; / Script & gt; & Lt; / Body & gt; & Lt; / Html & gt;

Everything works in Firefox and & lt; Em> Tag & lt; Strong> Has been replaced with

But in Opera & lt; Em> Also, any other HTML tags are not captured on regexps.

Is there any way to correct this behavior? Not only do I need to change tags, but also parsing their content (for example, href attributes) is needed.

Opera returns the tag as an uppercase, eg & lt; EM & gt; . You have to change your regular expressions in an insensitive way to work: 

  var string2 = string1.replace (/ & lt; em & gt; / gi, '& lt; strong & gt; ; ';); String 2 = string 2 Location (/  / gi, '& lt; / strong & gt;');

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
