Help need to find patterns in documents


I am very new to cluto so I am wondering if you can help me with this.And whether it is possible to approach my problem using cluto.

I have a set of documents. The documents have some information which can be divided into different sections.Each of the documents should have the same pattern.(eg. maybe different headings or tables which keep different type of information)
is it possible to cluster and find out what these sections should be and what should be the words in each section?

I am not trying to cluster the documents but trying to find out whether within the document there is any specific pattern that is being followed.
And also see if there is a hierarchy.

Basically I am trying to build a taxonomy.using these documents as reference.

Any kind of help would be greatly appreciated because i am totally new.

thanks a lot.

best regards,
