xslt - Converting and HL7 segment to XML -

i have xml able generate using hapi libraries , use xsl change format of xml. using following template. current template looks @ obx.5 segment digital value , interprets obx6 (units of measure). trying interpret obx6 when come 1 of clients in style duplicates caret ^ in between (ex: %^% or ml^ml). current template ignores able value of segment substring before or after ^.

<xsl:template match="hl7:obx.6[matches(./../hl7:obx.5, '^\d+(\.\d+)?$') , index-of($percentlist, .) or index-of($mgdllist, .) or index-of($mllist, .) or index-of($mmlist, .) or index-of($mglist, .))]">     <result><xsl:value-of select="./../hl7:obx.5" /></result>         <xsl:when test="index-of($percentlist, .)">             <units>%</units>         </xsl:when> ...         <xsl:when test="index-of($mllist, .)">             <units>ml</units>         </xsl:when>          <xsl:otherwise>             <units><xsl:value-of select="./hl7:ce.1" /></units>         </xsl:otherwise> ...  </xsl:template> 

the result should produce

            <result>38.0</result>             <units>%</units> 

from

                <obx.5>38.0</obx.5>                 <obx.6>                     <ce.1>%^%</ce.1>                 </obx.6> 

thanks in advance!

use:

tokenize(hl7:ce.1, '\^')[1] 

here simple xslt 2.0 - based verification:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"  xmlns:xs="http://www.w3.org/2001/xmlschema">  <xsl:output omit-xml-declaration="yes" indent="yes"/>   <xsl:template match="obx.6">   <xsl:sequence select="tokenize(ce.1, '\^')[1]"/>  </xsl:template>   <xsl:template match="text()"/> </xsl:stylesheet> 

when transformation applied on following xml document (derived provided xml fragment , made well-formed):

<t>     <obx.5>38.0</obx.5>     <obx.6>         <ce.1>%^%</ce.1>     </obx.6> </t> 

the wanted, correct result produced:

%
