hi all,

what's the best practice to check if a string is in a given range of possible values (i.e.: nin=10 max=zzzz)?

I'm currently using a series of calls to the following template:
However it doesn't give us the "natural" comparison result i.e. "10" is less than "5", we want "10" greater than "5".

thanks

<xsl:template name="stringCompare">
<xsl:param name="str1"/>
<xsl:param name="str2"/>
<xsl:choose>
<xsl:when test="str1=str2">
<xsl:text> equal </xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:variable name="thePair">
<xsl:element name="str1">
<xsl:value-of select="$str1"/>
</xsl:element>
<xsl:element name="str2">
<xsl:value-of select="$str2"/>
</xsl:element>
</xsl:variable>
<xsl:variable name="sortedPair">
<xsl:for-each select="msxsl:node-set($thePair)/*">
<xsl:sort select="."/>
<xsl:copy-of select="."/>
</xsl:for-each>
</xsl:variable>
<xsl:choose>
<xsl:when test="$str1 = msxsl:node-set($sortedPair)/*[1]">
<xsl:text> less than </xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text> greater than </xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

If you want to force it to be a string, try concatenating the same string to the front of both of them before comparing, eg. add a "a" in front.

I think we need to make them right justified pattern with spaces or some common char.
'000005' and '000010' this will work.
'a5' and 'a10' will give me the same wrong result. 'a10' is still less than 'a5'.

I was hoping to find some already made functions especially using the schemas-microsoft-com estension.

thanks

Sorry, I misinterpreted and was solving for the reverse problem.
Have you noticed that your test uses equals, as opposed to &lt;

Otherwise, cast each value to a number.
<xsl:variable name="num1">
<xsl:number value="$str1"/>
</xsl:variable>
<xsl:variable name="num2">
<xsl:number value="msxsl:node-set($sortedPair)/*[1]"/>
</xsl:variable>

<xsl:when test="$num1 = $num2">
<xsl:text>equals</xsl:text>
</xsl:when>
<xsl:when test="$num1 &lt; $num2">
<xsl:text>less than</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>greater than</xsl:text>
</xsl:otherwise>
