[XML4Lib] Style sheet question (UNCLASSIFIED)

[Binkley, Peter]

Do I understand rightly that the problem is here, where it trims the
(presumably) trailing period?

            <xsl:variable name="title"
select="substring-before($title_tmp, '.')" />

If there is no final period, that returns an empty string.

The answer would be to remove the final character only if it is a
period. This would do it:

	concat(
		substring($title_tmp, 1, string-length($title_tmp - 1),
		translate(
			substring($title_tmp, string-length($title_tmp),
1),	
			'.',
			''
		)
	)

(Indented for legibility). I may be off-by-one with those
string-lengths, but you get the idea: chop off the final character and
then use translate() to remove any unwanted punctuation.

Or a simpler approach: append a period, so that it will always be there
as a delimiter; if there already is one, the first one will be the
delimiter so the second one does no harm.

	substring-before(concat($title_tmp, '.'), '.')

So if the title ends with a question mark, that will be the last
character before the appended period and will be preserved.

I hope this helps

Peter

I'm trying to convert our digital library metadata to MARC so we can
upload the records to our local OPAC and to OCLC. I've hit a snag that
maybe someone can help me with. It involves the 245 tag and subfield b.
I created this call-template below and it seems to work okay with one
major exception that I've found so far. I haven't been able to get it to
handle correctly those instances where a title containing a subfield b
happens to end with a question mark. Can anyone offer any advice?

<!--title template-->
<xsl:template name="title_template">
      <xsl:param name="string" />
      <xsl:param name="field" />
      <xsl:param name="ind1" />
      <xsl:param name="ind2" />
      <xsl:param name="type" />
      <datafield>
         <xsl:attribute name="tag">
            <xsl:value-of select="$field" />
         </xsl:attribute>
         <xsl:attribute name="ind1">
            <xsl:value-of select="$ind1" />
         </xsl:attribute>
         <xsl:attribute name="ind2">
            <xsl:value-of select="$ind2" />
         </xsl:attribute>
       

         
         <xsl:choose>
            <!-- IF A Colon, STOP AT AN OPENING PAREN -->
            <xsl:when test="contains($string, ':')!=0">
               <subfield code="a">
                  <xsl:value-of select="substring-before($string, ':')"
/>:</subfield>
            </xsl:when>
            
            <!-- NO colons, commas JUST OUTPUT THE NAME -->
            <xsl:otherwise>
               <subfield code="a">
                  <xsl:value-of select="$string" />
               </subfield>
            </xsl:otherwise>
       
	   </xsl:choose>

         <!-- CAPTURE subfield b -->
      
         <xsl:if test="contains($string, ':')!=0">
            <xsl:variable name="title_tmp"
select="substring-after($string, ':')" />
            <xsl:variable name="title"
select="substring-before($title_tmp, '.')" />
            <subfield code="b">
               <xsl:value-of select="$title" /></subfield>
         </xsl:if>
   </datafield>
   </xsl:template>
