Hi,
Is there some easy way -- in XSLT 2.0 -- to handle in a general way
collapsing number ranges like:
23-24 => 23-4
333-334 => 333-34
7777-7778 => 7777-78
The source will be like:
<biblioref linkend="one" units="page" begin="23" end="24" />
Can't really see what you algorithm is, but here's a wild guess, just call
x:range('23-24')
<xsl:function name="x:range">
<xsl:param name="range" as="xs:string"/>
<xsl:variable name="first" select="substring-before($range, '-')"/>
<xsl:variable name="second" select="substring-after($range, '-')"/>
<xsl:sequence select="concat($first, '-', x:remove($first, $second, 1))"/>
</xsl:function>
<xsl:function name="x:remove">
<xsl:param name="s1" as="xs:string"/>
<xsl:param name="s2" as="xs:string"/>
<xsl:param name="i" as="xs:integer"/>
<xsl:sequence select="if (substring($s1, $i, 1) = substring($s2, $i, 1))
then x:remove($s1, $s2, $i + 1)
else
if (string-length($s2) < 3)
then substring($s2, $i)
else substring($s2, $i - 1)"/>
</xsl:function>
