Please add a little more examples

First of all: THANK YOU! Absolutely terrific program. I love it.

I had only a little troubles with figuring out how to do traversing up/down through the nodes, so I had to make some wild guesses and finally I found it out.

Examples (wrong) -- first part of concat:
xml sel -t -m //doc -m texts -m text -v concat\(parent::text::@id,self::text\) -n -b -b radiology.xml
xml sel -t -m //doc -m texts -m text -v concat\(parent::parent::@id,self::text\) -n -b -b radiology.xml
xml sel -t -m //doc -m texts -m text -v concat\(root::@id,self::text\) -n -b -b radiology.xml

And finally I thought that I ought to exactly traverse the tree, but then I had problems to get id:
xml sel -t -m //doc -m texts -m text -v concat\(parent::texts/parent::doc[@id],self::text\) -n -b -b radiology.xml

And luckily -- bingo:
xml sel -t -m //doc -m texts -m text -v concat\(parent::texts/parent::doc/@id,self::text\) -n -b -b radiology.xml

Such example if found on web page could save some time for me and other users.
