lotus xsl supports variables. probably you are looking at the value of
the variable outside the scope where it is bound.
A common mistake is
<xsl:if test="something">
<xsl:variable name="x" select="something_else"/>
<xsl:if>
...$x ...
which doesn't work as the scope of the binding of $x ends at the
element containing the binding, ie the </xsl:if> here.
<file previous_date="03/13/99">
<file_date>04/03/99</file_date>
</file>
you don't say which node you try to evaluate this on:
<xsl:if test="file_date[not(. = @previous_date)]"> do something </xsl:if>
If you are on the file node then the string value of `.' will include
that white space, in which case you might want to use normalize-space(.)
but safer would be normalize-space(file_date)= @previous_date
(normalize-space() may be called normalize() if your xsl processor is
older than a couple of weeks or so)
If you are on the file_date node, the nyou want
normalize-space(.)=normalize-space(../@previous_date)
The normalize-space() can be omitted if you know there is never any
white space in these strings.

I'm using the LotusXSL processor. lotus xsl supports variables. probably you are looking at the value of the variable outside the scope where it is bound.
