How to insert some text into the string ?

<%
 String strTest = new String();
 int intPos = 1;
 
 strTest = "<SPAN id='" + intPos + "' CLASS=obj97BF5 STYLE=\"position:absolute; left:0.000in; top:0.000in; height:1.073in\";}\">";
 intPos++;
 strTest += "<SPAN id='" + intPos + "' CLASS=obj97BF6 STYLE=\"position:absolute; left:0.052in; top:0.833in; width:2.771in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test1\" >Test1</A></SPAN>";
 intPos++;
 strTest += "<SPAN id='" + intPos + "' CLASS=obj97BF6 STYLE=\"position:absolute; left:2.905in; top:0.833in; width:2.500in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test2\">Test2</A></SPAN>";
 intPos++;
 strTest += "<SPAN id='" + intPos + "' CLASS=obj97BF8 STYLE=\"position:absolute; left:7.052in; top:0.833in; width:1.645in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test3\">Test3</A></SPAN>";
 strTest += "</SPAN>";
%>

oops, everywhere you see this:


   "<SPAN id='" + intPos + "'


change it to this:


   "<SPAN id='id" + intPos + "'

I don't want to do that.

I want to scan the string and use substring method to
insert id=idx.

ok, so this is cleaner:


<%
 String strTest = new String();
 int intPos = 1;
 
 strTest = "<SPAN id='id" + (++intPos) + "' CLASS=obj97BF5 STYLE=\"position:absolute; left:0.000in; top:0.000in; height:1.073in\";}\">";
 strTest += "<SPAN id='id" + (++intPos) + "' CLASS=obj97BF6 STYLE=\"position:absolute; left:0.052in; top:0.833in; width:2.771in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test1\" >Test1</A></SPAN>";
 strTest += "<SPAN id='id" + (++intPos) + "' CLASS=obj97BF6 STYLE=\"position:absolute; left:2.905in; top:0.833in; width:2.500in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test2\">Test2</A></SPAN>";
 strTest += "<SPAN id='id" + (++intPos) + "' CLASS=obj97BF8 STYLE=\"position:absolute; left:7.052in; top:0.833in; width:1.645in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test3\">Test3</A></SPAN>";
 strTest += "</SPAN>";
%>

ooooh, stand by

You can use this function to do this:

<%!
 int intPos = 0;

 String nextPos()
 {
    return String.valueOf(++intPos);
 }

 String strReplace( String str, String srch, String repl )
 {
    if ( str==null || srch==null || repl==null )
       return str;

    int ndx = str.indexOf(srch);
    StringBuffer buffer = new StringBuffer(str);

    while ( ndx >= 0 )
    {
        buffer.replace(ndx,(ndx+srch.length()),repl);
        ndx = buffer.toString().indexOf(srch);
    }

    return buffer.toString();
 }

//then do this:

strTest = strReplace( strTest, "<SPAN ", "<SPAN id='"+nextPos()+"' " );

%>

no, that won't work, sorry.  Can you build the string one SPAN at a time?  Or are you reading in an entire document all at once?

Does this work?
<%
 String strTest = new String();
 strTest = "<SPAN CLASS=obj97BF5 STYLE=\"position:absolute; left:0.000in; top:0.000in; height:1.073in\";}\">";
 for (int intPos = 1; intPos < 3; intPos ++) {
 strTest += "<SPAN ID=\"" + intPos + "\" CLASS=obj97BF" + (intPos + 5) + " STYLE=\"position:absolute; left:0.052in; top:0.833in; width:2.771in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test" + intPos + "\" >Test" + intPos + "</A></SPAN>";
 }
%>

I got this error :

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred between lines: 21 and 50 in the jsp file: /t.jsp

Generated servlet error:
D:\Program Files\Apache Tomcat 4.0\work\localhost\examples\t$jsp.java:39: Identifier expected.
        strTest = strReplace(strTest, "<SPAN ", "<SPAN id='"+nextPos()+"' " );
               ^
1 error

try this:

String addID( String str )
 {
    if ( str==null )
       return str;

    String srch = "<SPAN ";
    String repl = srch + "id='";

    int ndx = str.indexOf(srch);
    int intPos = 0;

    StringBuffer buffer = new StringBuffer(str);

    while ( ndx >= 0 )
    {
        buffer.replace(ndx,(ndx+srch.length()),repl+String.valueOf(++intPos)+"' ");
        ndx = buffer.toString().indexOf(srch);
    }

    return buffer.toString();
 }

strTest = addID(strTest);

doooooh!

change this:

   ndx = buffer.toString().indexOf(srch);

to this:

   ndx = buffer.toString().indexOf(srch,ndx+1);

This is very inelegant, but:

-----------
<%
 String strTest = new String();
 int intPos = 0;
 
 strTest = "<SPAN CLASS=obj97BF5 STYLE=\"position:absolute; left:0.000in; top:0.000in; height:1.073in\";}\">";
 strTest += "<SPAN CLASS=obj97BF6 STYLE=\"position:absolute; left:0.052in; top:0.833in; width:2.771in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test1\" >Test1</A></SPAN>";
 strTest += "<SPAN CLASS=obj97BF6 STYLE=\"position:absolute; left:2.905in; top:0.833in; width:2.500in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test2\">Test2</A></SPAN>";
 strTest += "<SPAN CLASS=obj97BF8 STYLE=\"position:absolute; left:7.052in; top:0.833in; width:1.645in\";}\">";
 strTest += "<A HREF=\"\" NAME=\"test3\">Test3</A></SPAN>";

 String strFinal = "";
 char[] charTest = strTest.toCharArray();
 int spanCtr = 0;
 
 for( int i = 0, x = charTest.length; i < x; i ++ ) {
    if( charTest[ i ] == 'S' && charTest[ i + 1 ] == 'P' && charTest[ i + 2 ] == 'A' && charTest[ i + 3 ] == 'N' ) {
        strFinal += "SPAN id=\"id" + ( ++ spanCtr ) + "\"";
        i += 3;
    }
    else {
        strFinal += "" + charTest[ i ];
    }
 }

oops, that added it to the closing tags too. Try this:

------------

int intPos = 0;

           charTest[ i + 4 ] == 'N' ) {
