Compare to just PHP->XHTML? life is full of tradeoffs. my understanding is there is a tradeoff between simplicity / complexity and performance / mantainability. so if youre trying to build something small that runs fast you can use the standard PHP facility, ie <?php $myName = 'nathan'; ?> <html> <head> <title> this is my page </title> <body> my name is <?=$myName?> there are other approaches as well; i personally prefer building the html as a string, so the previous example would become <?php $htmlOut = '$myName = 'nathan'; <html> <head> <title> this is my page </title> <body> my name is ' . $myName; echo $htmlOut; ?> some people even build templating systems around these core PHP facilities. but when building a large site templating systems facilitate the separation between PHP and XHTML youre looking for. i havent used Smarty, though ive looked at it. one of the big issues it presents is it is basically its own little language, because logic can be embedded within a template. so for instance, if you want to build an HTML table and you have several rows worth of content in an array, lets say, you could loop over the array within the template producing the rows during said iteration. so there is this issue where a mistake could be made in the logic thats embedded in a Smarty template, which begs the awesome question, how do you debug a Smarty template? so, truth be told, logic can be embedded in an xsl file as well. really you just need to create a set of conventions that dictate how much logic, if any, will be allowed in template files. that must be enforced for all development on your site; the same could be done for a site built using Smarty. and also, i suppose there is an issue w/ broken logic in XSL templates as well. but the main reason i prefer XSL is because its a W3C standard whereas Smarty is not. also, XSL can be used w/ any language, not just PHP so i feel i am more valuable knowomg i might be able to use XSL w/ other languages on other projects like java or .net or w/e. i will send a sample when i get home, im at the office right now. -nathan On 7/7/07, Kelvin Park < kelvinpark86@xxxxxxxxx> wrote:

Yes, I would like to receive a sample of SimpleXML/DOM/XML. Thanks!
