How to invoke a funtion on a custom tag value?

Question

Hello,
I have a custom tag used in my code.
It is used as follows:
<b:testtag name="Title"/>
This outputs a String value.
This is used in my HTML as follows:
<b:testtag name="Title"/>
This part of the code works fine. However i now want to invoke some funtion on the String outputted before actually outputing it. To be more specific, i need to convert the string to uppercase before outputting it.
So my question is, Is there anyway to directly invoke the String.toUpperCase method on the tag output?
If not, another way of achieving this is to store the value returned by the custom tag into a java String variable in a scriplet code, and invoke the String.toUpperCase method.
Any idea how to go about with this? Particularly, i would like to know if it is possible to store the value outputted by the tag into a java variable in a scriplet code?
If not is there any other way of converting the tag output value to uppercase?
Please help!
Thanks in advance

Answer 1

Solution one: Change your tag so it outputs in uppercase
Solution two: use a tag from a String taglib and put that tag around your tag
example taglib:
http://jakarta.apache.org/taglibs/doc/string-doc/intro.html
example bit of code
<a href='some test url here'><str:upperCase><b:testtag name="Title"/></str:upperCase></a>
