I am new to this and no doubt have gotten into something a little over my head
but
I've always believed in the "sink or swim" method of self teaching.
This XSL and XML are extracts of a much larger project of mine where the user
has
an input form (another stylesheet) that is read and then passes parameters to
this
stylesheet so it can use the contains() function to search the xml document
based
on the parameters passed.
I'm trying to learn how/do two things here:
1) If the user searches for "Data" ($searchtext = "Data") the output should also
include the fourth record because Field1 contains "all".
2) This stylesheet should also not display any records where Field1 contains
"info".
I have a seperate stylesheet that will do that using the same method that is
used to solve problem #1. This user doesn't have any links to the stylesheets
that
would allow him to view a stylesheet that can view "info" records. I also have
the
permissions of that stylesheet set so this user can't read them either. So
security
is not a consideration here.
Also I didn't include any attempts I've made in trying to accomplish this
because
nothing has worked so far. I have, however, been able to use the line below in
the
"textsearch" template to perform the "all" search but it is sloppy in that
"all" is
not processed by the "Case Conversion" variable. (I wish it was.) I have not
been
able to figure out if or how I might use the "not()" function to exclude
outputting
"info" records.
<xsl:for-each select="record[*[name() = $searchfield][contains(., $ProperText)
or contains(., $UCASETEXT) or contains(., $lcasetext) or ../Field1[contains(.,
'ALL') or contains(., 'all') or contains(., 'All')]]]">
XML Data
This is only a snippet of a much larger XML file normally kept in a separate
file
that is read by an ASP VBScript using the "Msxml2.FreeThreadedDOMDocument.4.0"
Load
method and parameters are output via the "MSXML2.XSLTemplate.4.0" AddParameter
method.
