Question

Hi
I need get array of elements (before “-“ if exist) by xsl.

xml is

<Cars>
<Car Trunck="511"/>
<Car Trunck="483-20"/>
<Car Trunck="745"/>
</Cars>

xsl is

<xsl:variable name="testarr">
<xsl:for-each select="//Cars//Car/@Trunck">
<xsl:value-of select="number(substring(.,1,3))" />
                </xsl:for-each>
                        </xsl:variable>

(i suppose that all numbers is three-digit number, if someone knows a solution for all conditions will be glad to hear the proposal)
if i do this
i get all numbers in one line: 511483745
and i need get them in array
because i also need get the max value

thanks

You could use the substring-before and substring-after functions: See the excellent ZVON tutorial
http://zvon.org/xxl/XSLTreference/Output/function_substring-after.html

In your example you are only extracting the values (which are strings) which get concatenated. Perhaps you need to wrap the result in your own element

<xsl:for-each select="//Cars//Car/@Trunck">
  <truck>
    <xsl:value-of select="number(substring(.,1,3))" />
  </truck>
</xsl:for-each>
