In XSLT 2.0 if you have the start and end of the range as integers $start
and $end, you can do
<xsl:value-of select="for $i in $start to $end return concat('fig', $i)"/>
In 1.0 you have to do a call on a named template that calls itself
recursively to process each number in the sequence.

Subject: [xsl] Expanding Ranges
Dear All,
My input is like below: the <cross-ref> tags are not
continues it will come in between the content.
<links>
<p>some text <cross-ref><cr refid="MEPRfig2"> 2</cr>-<cr
refid="MEPRfig4">4</cr></cross-ref> some text <cross-ref><cr
refid="MEPRfig1">Figures 1</cr> and <cr
refid="MEPRfig3">3</cr></cross-ref> some text</p>
<p><cross-ref><cr refid="MEPRtbl1">1</cr>-<cr
refid="MEPRtbl4">4</cr></cross-ref> some text <cross-ref><cr
refid="MEPRtbl1">Tables 1</cr> and <cr
refid="MEPRtbl2">2</cr></cross-ref> some text <cross-ref><cr
refid="MEPRtbl1">Table1</cr></cross-ref> some text </p>
<p>some text <cross-ref><cr refid="MEPRtbl1">1</cr>-<cr
refid="MEPRtbl3">3</cr> and <cr refid="MEPRtbl4">4</cr></cross-ref>
some text</p>
</links>
The required output will be like below:
<links>
<p>some text <cross-refs refid="fig2 fig3 fig4">
2-4</cross-refs> some text <cross-refs refid="fig1
fig3">Figures 1 and 3</cross-refs> some text</p>
<p><cross-refs refid="tbl1 tbl2 tbl3 tbl4">1-4</cross-refs>
some text <cross-refs refid="tbl1 tbl2">Tables 1 and
2</cross-refs> some text <cross-ref
refid="tbl1">Table1</cross-ref> some text </p>
<p>some text <cross-refs refid="tbl1 tbl2 tbl3 tbl4">1-3 and
4</cross-refs> some text</p> </links>
Here is the XSL which i have tried. I do not know how to
expand the ranges. My style sheet is combining available
attributes to single attribute. Please help me in getting
ranges expanded.
<xsl:template match="cross-ref">
<xsl:choose>
<xsl:when test="count(cr) = 1">
<cross-ref refid="{substring-after(cr/@refid,'MEPR')}">
<xsl:apply-templates/>
</cross-ref>
</xsl:when>
<xsl:otherwise>
<cross-refs>
<xsl:attribute name="refid">
<xsl:for-each select="cr">
<xsl:value-of
select="substring-after(@refid,'MEPR')"/>
<xsl:if
test="position() != last()">
<xsl:text> </xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:attribute>
<xsl:apply-templates/>
</cross-refs>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="cr">
<xsl:apply-templates/>
</xsl:template>
Regards,
Ganesh
