newbie q: xml to txt - please help!

hi all,
TASK: i want to exctract certain data from a xml-file, which contains programdetails of several tv channels, and put it into a txt-file (one textfile for each tvchannel). the programm should read from the xml file the data starting from 6:00 am of the next day till 5:59 am of the day after that. (this will be executed once a day for every following day.) 

QUESTIONS: can my problem be solved with xsl/xslt, or do i need another programminglanguage (vbscript or c)? how will get xsl sysdate? there are 22 tvchannels in the xmlfile, for every channel i need a different textfile. how to pass parameter?
thanx!

		<xsl:if test = "DURATION[@time!='00:00']">
