Analysis of the Unicode entity encoding and conversion code by using corner stone

This article briefly introduces the code for converting the unicode entity encoding of html by using corner stone. When developing a browser using corner stone, we need to convert the unicode entity encoding of html to display it normally.

How to convert the unicode entity encoding in html by using corner stone

During the development of the j2's browser, we need to convert the unicode entity encoding of html for normal display. See the following code:

 
 

  
  
<Ahrefahref = "http://wap.monternet.com/"> back to mxnet </a> <br/>
  
  
 
 
 

The method is as follows:

 
 

  
  
PrivatestaticStringdecodeUnicode (finalStringdataStr ){
  
  
Intstart = 0;
  
  
Intend = 0;
  
  
FinalStringBufferbuffer = newStringBuffer ();
  
  
While (start>-1 ){
  
  
Intsystem = 10; // hexadecimal
  
  
If (start = 0 ){
  
  
Intt = dataStr. indexOf ("&#");
  
  
If (start! = T) start = t;
  
  
}
  
  
End = dataStr. indexOf (";", start + 2 );
  
  
StringcharStr = "";
  
  
If (end! =-1 ){
  
  
CharStr = dataStr. substring (start + 2, end );
  
  
 
  
  
// Judge the base
  
  
Chars = charStr. charAt (0 );
  
  
If (s = 'X' | s = 'X '){
  
  
System = 16;
  
  
CharStrcharStr = charStr. substring (1 );
  
  
}
  
  
}
  
  
// Conversion
  
  
Try {
  
  
Charletter = (char) Integer. parseInt (charStr, system );
  
  
Buffer. append (newCharacter (letter). toString ());
  
  
} Catch (numberformateffectione ){
  
  
E. printStackTrace ();
  
  
}
  
  
 
  
  
// Process non-unicode characters between the current unicode Character and the next unicode Character
  
  
Start = dataStr. indexOf ("& #", end );
  
  
If (start-end> 1 ){
  
  
Buffer. append (dataStr. substring (end + 1, start ));
  
  
}
  
  
 
  
  
// Process the last non-unicode Character
  
  
If (start =-1 ){
  
  
Intlength = dataStr. length ();
  
  
If (end + 1! = Length ){
  
  
Buffer. append (dataStr. substring (end + 1, length ));
  
  
}
  
  
}
  
  
}
  
  
Returnbuffer. toString ();
  
  
}
