I have the following XML

<ServInfo CMD="011">
      <Serv Code="ED" Type="RED">
      <Text>AS KK1 06L18MAR/CHAIR/ACCPT/USD2000/100RC CCVIXXXXXXXXXXXX0001EXPXXXX 8312312270746</Text>
      </Serv>
      
I want to obtain the the last field in <text> = 8312312270746. I have following but I don't think I"m referencing the @CMD correctly bc it errors out.

<xsl:variable name="test"  select ="//Itin/ServInfo[Serv[@Code='ED' and @Type = 'RED']/@CMD=$id/Text "  />

where $id = 11

<xsl:variable name="test"  select ="//Itin/ServInfo[Serv[@Code='ED' and @Type = 'RED']][@CMD=$id]/Text "  />

but I would force the attribute to a number to make sure it is numeric equality you get

<xsl:variable name="test"  select ="//Itin/ServInfo[Serv[@Code='ED' and @Type = 'RED']][number(@CMD) = number($id)]/Text "  />

for getting the last component in XSLT2
<xsl:value-of select="tokenize(normalize-space($test), ' ')[last()]"/>

in XSLT1 you will need to use recursion

i used XSLT1.

<xsl:variable name="test"  select ="//Itin/ServInfo[Serv[@Code='ED' and @Type = 'RED']][number(@CMD) = number($id)]/Text "  />

and the Text wasn't found.

XML input:
<ServInfo CMD="011">
      <Serv Code="ED" Type="RED">
      <Text>AS KK1 06L18MAR/CHAIR/ACCPT/USD2000/100RC CCVIXXXXXXXXXXXX0001EXPXXXX 8312312270746</Text>
      </Serv>
</ServInfo>      

If I do
<xsl:variable name="test"  select ="//Itin/ServInfo[Serv[@Code='ED' and @Type = 'RED']]/Serv/Text "  />
I can obtain all instances of Text where condition is satisfied.

But once i add the filter of the @CMD, nothing is found.  
<xsl:variable name="test"  select ="//Itin/ServInfo[Serv[@Code='ED' and @Type = 'RED']][number(@CMD) = number($id)]/Text "  />

Text is not a child of ServInfo, you need a Serv in between

    <xsl:variable name="test"  select ="//Itin/ServInfo[Serv[@Code='ED' and @Type = 'RED']][number(@CMD) = number($id)]/Serv/Text "  />

Aha, you seem to have come to the same conclusion...

what is the logic for that last bit? Last 8 characters, numbers after the last space?

The logic would be to obtain the value after the last space in text node.

Then you need to add a recursive template

   <xsl:variable name="id">11</xsl:variable>
    <xsl:variable name="test"  select ="//Itin/ServInfo[Serv[@Code='ED' and @Type = 'RED']][number(@CMD) = number($id)]/Serv/Text "  /> 
    
    <xsl:template match="/">
        <xsl:call-template name="get-part-after-last-space">
            <xsl:with-param name="str" select="normalize-space($test)"/>
        </xsl:call-template>
    </xsl:template>
    
    <xsl:template name="get-part-after-last-space">
        <xsl:param name="str"/>
        <xsl:choose>
            <xsl:when test="contains($str, ' ')">
                <xsl:call-template name="get-part-after-last-space">
                    <xsl:with-param name="str" select="substring-after($str, ' ')"/>
                </xsl:call-template>
            </xsl:when>
            <xsl:otherwise>
                <xsl:value-of select="$str"/>
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>
