Hi Roger,
I am happy to be programming in XSLT. I am happy to be working at the
abstraction of symbols (strings, string manipulations, elements,
attributes) and not numbers. I am happy that the XSLT processor takes
care of memory management for me.
you have to pay a price for this -- execution speed.
I am happy to be working at the abstraction of tree navigation (parent,
ancestor, child, descendant, sibling traversals) and not pointers.
You can have "XSLT pointers" as well ;-)

Subject: [xsl] After a refresher on C programming, I have a greater
appreciation for XSLT
Hi Folks,
Lately I have been refreshing my memory on C programming (because a book
that I am reading gives its examples in C).
Reading the C book has given me a better appreciation for the advances that
have been made in modern programming languages. Here are a few things that
struck me as I read the C book:
- In C most things are treated as numbers. Characters are treated as
numbers (you can even perform arithmetic on characters). Logical values
(true/false) are treated as numbers.
- Memory management is of concern to a C programmer. C programmers need to
ensure that the code doesn't reference past the end of an array. A
programmer must ensure that performing arithmetic on a variable does not
produce a value that exceeds the allotted memory for the variable (thereby
resulting in "buffer overflow"). A programmer may call a function to find
out the amount of memory being used (sizeof) by an array or call a function
to allocate a certain quantity of memory (malloc).
- Pointers must be carefully managed and care must be taken when traversing
the pointers.
I am happy to be programming in XSLT. I am happy to be working at the
abstraction of symbols (strings, string manipulations, elements,
attributes) and not numbers. I am happy that the XSLT processor takes care
of memory management for me. I am happy to be working at the abstraction of
tree navigation (parent, ancestor, child, descendant, sibling traversals)
and not pointers.
/Roger
