How to escape special characters through JAVA

[ikilldeath]

For eg:

 public String DisplayinURLFormat(String sampleString,int urlIndex)
    {
          String tempString = "";
             int beginIndex = sampleString.indexOf("http", urlIndex); 
             if(beginIndex!=-1)
             {
                 int endIndex = sampleString.indexOf(' ', beginIndex);
                 if(endIndex==-1)
                 {
                     endIndex = sampleString.length();
                 }
                 String hyperString = sampleString.substring(beginIndex,endIndex);
                 tempString = sampleString.substring(0, beginIndex)+"<a href='" + hyperString + "'>"+hyperString+"</a>" + sampleString.substring( endIndex,sampleString.length());
                 urlIndex = endIndex + hyperString.length() + 13;
                 sampleString= tempString;
                 return DisplayinURLFormat(sampleString,urlIndex);  
             }
             else
                 return sampleString;
    }
 

Here i am making a string to URl if the string containd any http format.

like if i enter sampleStruing as "go to http://www.google.com" the http string shud appear in URl. but for this i need to use the escapeXml flag in HTML to ignore the conversion of < and > characters. Is there any other way to make the escaped in JAV code itself

Err, I'm no XML/web man myself, so I don't know exactly what this kind of escape thing is you're talking about.
However, could you perhaps give a couple of example input-Strings and desired output-String? Perhaps then I can give you a hand.

OK, I have a string sampleString which contains a substring which is supposed to be printed in URL format, for that i have written the above function.

But anyhow i needed to use the escapeXml flag to set it to false in the jsp page not to convert the <a ref> tag to &lt;a ref &gt;.
The problem doing this is it may escape some of the valid tags which i dint want to escape. Here i want only <a ref></a> tags to be escaped

Could you provide examples of in- and output?
For example: String "aaaaaaaabbbbbbbbbbbbbbssssssssssssssssssbbbb" comes in, and "aaaaaaaabbbXXXXXXXbbsssssXXXXXssssssssbbb" should come out.

[ikilldeath]

"go to <a href='http://www.google.com'></a>" is input

"go to &lt;a href='http://www.google.com'&gt; &lt;/a&gt;" is the out put

[ikilldeath]

but the output should be

"go to http://www.google.com "

[prometheuzz]

but the output should be

"go to http://www.google.com "

Output to what? Are we talking about Java here?

[prometheuzz]

"go to <a href='http://www.google.com'></a>" is input

"go to &lt;a href='http://www.google.com'&gt; &lt;/a&gt;" is the out put

Look at String's replaceAll(...) method.

Yeah, regexps! Gimme an 'r'! gimme an 'e'! gimme a 'g'! gimme an 'e'! ... erm,
sorry; it won't happen again.

kind regards,
