You really need to read the svnbook mentionied by schlenk.

svn co svn://svn.fazend.com/abc/branches/pqr-staging pqr

Check out from the mentioned repository and put the files in (a new) pqr directory. The new directory is your working copy.

cd pqr

Change to the pqr directory.

svn merge ^/trunk/xyz.com

Merge the changes from a different working copy (^/trunk/xyz.com) into your working copy (pqr). The only reasonable explanation for the ^ I can find is "parent directory" on RISC OS.

do some changes in here and

Make additional changes in the working copy, usually needed to resolve any conflicts.

svn ci -m " some comment about your change"

Commit the merge result and your changes to the repository.
