How change a string in a CLOB field

Question

Hi all,
I'm trying to explain my problem.
I use an Asp procedure to load a html text in a Clob field.
The simple algoritm is:
- The first time that I visit the web address, I write in a field
Desc_Webb_Attu --> CLOB
- The second time that I visit the web address, I write in a field
Desc_Webb_Attu_Temp --> CLOB
- I see if there are differences between the first and the second visit, using this statment
SELECT      dbms_lob.compare(Desc_Webb_Attu,Desc_Webb_Attu_Temp)
From table
The procedure run ok, but in the case of web addresses have a banner, counter or reloy, I'll have always that the web address will be modified :(
I'm thinking to do in this way:
If I can know where is the string of data (for example) I would change this string with blank, after to use the stament "compare".
Do you know if is a statment or a procedure (I use Pl/sql) to resolve this?
I hope that I have explained good
Thank's for any suggestion

for(i=0;arr!=null;i++)
That's an infinite loop.OP: when you post code, use the code tags described here:
http://forum.java.sun.com/help.jspa?sec=formatting
The idea is that you put [code] at the start of your code and [/code]
at the end. That way something like:
[code]if(tagsUsed) {
    System.out.println("Output is nice.");
}[/code]
ends up displayed asif(tagsUsed) {
    System.out.println("Output is nice.");
}This is especially important when arrays are used because otherwise
bits of your your code "dissappear" (as you have found) and this causes
confusion.
