String Tweaking

[Srikkanth Mohan]

Hi all,

I need to delete and update a StringBuffer.My change is something like this

Before:
<LI class="someclass">Test12<UL>

After Tweaking

<LI class="selected">Test12<UL style="display:block'>

Till now i've been able to change the first part of the class, with something like this
, j refers to the start index of the String.

   int end="<LI class=\"someclass\">".length();
sb.delete(j,j+end);
sb.insert(j,"<LI class=\"selected\">"); 

But I'm not able to do the second part of the massagin.

I tried this ,sb is a reference to the same Buffer

 int disp=sb.indexOf("<LI class=\"selected\">Test12<UL>" );
String dispend="<LI class=\"selected\">Test12";
int dispend=dispent.length();
sb.delete(disp+dispend,disp+dispend+4);
//+4 done for</UL>
sb.insert(disp+dispend,"<UL style=''>");
   

But this doesn't work. Can you help me on this? Any better ways to do this?

I think you could do better using the replace() method.

Somewhat like this:

sb = new StringBuffer("<LI class=\"someclass\">Test12<UL>");
int index = sb.indexOf("someclass");
sb.replace(index,index+"someclass".length(),"selected");

And somewhat similar for the other part.

I think you'd ultimately be best server to learn one of the XML packages that helps manipulate/model XML.
