Marcy,
The trouble you are having is resulting from this bit of code:
At 12:01 PM 2/24/2005, you wrote:
<xsl:variable name="title">
<xsl:choose>
<xsl:when test="contains($file_title,'_')">
<xsl:value-of
select="escape-uri(substring-before($file_title,'_'),true())"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="escape-uri($file_title,true())"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<xsl:variable name="title2">
<xsl:choose>
<xsl:when test="contains($title,' ')">
<xsl:value-of select="substring-before($title,' ')"/>
<xsl:text>.xml</xsl:text>
</xsl:when>
<xsl:when test="contains($title,'/')">
<xsl:value-of select="substring-before($title,'/')"/>
<xsl:text>.xml</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$title"/>
<xsl:text>.xml</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
This is what implements the logic you have described. Since the declaration
of $file_title has already converted new-lines into '_', these variable
declarations serve basically to trim the name further, ultimately taking
whatever string is available up to '_' or ' ' as a code to use for the
filename.
The logic is implemented well enough, but of course it's faulty given the
requirement, for the reason you outline: files stepping on each other
because names are not unique. So you need some other way of generating a
unique code for each file.
This is a very open-ended requirement, and only you decide what kind of
code would serve. Any ideas? If you were to ask the list what we have done
in analogous situations, I'm sure there would be many answers. In
particular, the questions come up of whether you need the file names to be
transparent, and how long you are willing to let them get. (It's not hard
to make them unique and either short or transparent, but generally harder
to do all of these together.) Note that until a functional specification is
clear, this isn't really an XSLT question. :->
I hope this helps,
Wendell
