How to print whole task Instance

Question

Hello everyone,
I know how to see an unfinished taskInstance from /idm/debug URL. It shows all the steps executed so far. Can i print the same TaskInstance using trace='true' in my code?
If yes, can you please let me knoe the code?
When i use :
<block trace="true">
<invoke name='getTask'>
<ref>WF_CONTEXT</ref>
</invoke>
</block>
It prints: "TaskInstance:TASK90F8BC7FBBFA7424:3908423C:1331B5D54A9:-7E55"
I want to print the whole taskInstance XML not just the ID.
Thanks in advance
