Question

I am looking for some help with XSLT to transform one xml file into another format.

The input xml file is below:

<PATIENTLIST ELAPSEDMS="234" >
    <PATIENT ID="MGH000007">
        <ADDRESS1>550 BREZHNEV ST</ADDRESS1>
        <ADDRESS2></ADDRESS2>
        <CITY>MOSCOW</CITY>
        <STATE>MA</STATE>
        <ZIP>02139</ZIP>
        <COUNTRY ISO3166-1="USSR"></COUNTRY>
        <DATEOFBIRTH>1934/04/10</DATEOFBIRTH>
        <DAYPHONE>[phone] </DAYPHONE>
        <FIRSTNAME>TEST</FIRSTNAME>
        <HOMEPHONE>[phone]</HOMEPHONE>
        <LASTNAME>TEST MGH</LASTNAME>
        <LIMITEDACCESS>False</LIMITEDACCESS>
        <MARITALSTATUS>SINGLE</MARITALSTATUS>
        <MEDICALRECORDNUMBERS>
            <MEDICALRECORDNUMBER>
                <SITE>BWH</SITE>
                <STATUS>A</STATUS>
                <VALUE>0000007</VALUE>
            </MEDICALRECORDNUMBER>
            <MEDICALRECORDNUMBER>
                <SITE>BWI</SITE>
                <STATUS>A</STATUS>
                <VALUE>0000007</VALUE>
            </MEDICALRECORDNUMBER>
            <MEDICALRECORDNUMBER>
                <SITE>MEEI</SITE>
                <STATUS>A</STATUS>
                <VALUE>0000007</VALUE>
            </MEDICALRECORDNUMBER>
            <MEDICALRECORDNUMBER>
                <SITE>MGH</SITE>
                <STATUS>A</STATUS>
                <VALUE>0000007</VALUE>
            </MEDICALRECORDNUMBER>
            <MEDICALRECORDNUMBER>
                <SITE>SHC</SITE>
                <STATUS>A</STATUS>
                <VALUE>0000007</VALUE>
            </MEDICALRECORDNUMBER>
            <MEDICALRECORDNUMBER>
                <SITE>OLD #</SITE>
                <STATUS>M</STATUS>
                <VALUE>0000007</VALUE>
            </MEDICALRECORDNUMBER>
        </MEDICALRECORDNUMBERS>
        <MIDDLEINITIAL>R</MIDDLEINITIAL>
        <MOTHERSMAIDENNAME></MOTHERSMAIDENNAME>
        <MRNR>0000007</MRNR>
        <NAME>TEST MGH, TEST R</NAME>
        <NAMESUFFIX></NAMESUFFIX>
        <NAMEPREFIX></NAMEPREFIX>
        <PRIMARYCAREPROVIDERID>512513</PRIMARYCAREPROVIDERID>
        <PRIMARYLANGUAGE>ENGLISH</PRIMARYLANGUAGE>
        <RACE CODE1="BLACK" CODE2="" FREETEXT="">BLACK</RACE>
        <ETHNICITY CODE1="AFRICAN AMERICAN" CODE2="" FREETEXT="">AFRICAN AMERICAN</ETHNICITY>
        <RELIGION>NO PREFERENCE</RELIGION>
        <SEX>M</SEX>
        <SSN></SSN>
        <UID>101662537</UID>
        <VETERAN>NO</VETERAN>
    </PATIENT>
</PATIENTLIST>

The output file needs to look like:

<?xml version="1.0" encoding="utf-8" ?>
<eCliPSEDataIntegrationServiceRequest xmlns="http://iocent.com/eCliPSEDataIntegrationServiceRequest.xsd">
    <PatientIdentifierRecord MedicalRecordNumber="MGH000007" LastName="Person" FirstName="Test" MiddleInitial="A" DateOfBirth="04/10/1934" Operation="Add" OverwriteExistingData="true" />
    <PatientDataRecord MedicalRecordNumber="MGH000007" ParameterName="Gender" ParameterValue="2" TimeStamp="8/30/2011" Operation="Add" OverwriteExistingData="true" />
    <PatientDataRecord MedicalRecordNumber="MGH000007" ParameterName="Race" ParameterValue="1" TimeStamp="8/30/2011" Operation="Add" OverwriteExistingData="true" />
</eCliPSEDataIntegrationServiceRequest>

So I am looking to pull out the

Patient ID and use it as the MedicalRecordNumber= value

DATEOFBIRTH node as the DateOfBirth value – with format changed from YYYY/MM/DD to MM/DD/YYYY

FIRSTNAME node becomes value for FirstName

LASTNAME node becomes value for LastName

MIDDLEINITIAL node becomes value for MiddleInitial

SEX node becomes value for Gender Male=1, Female=2

RACE node becomes Value for Race – based on a lookup table (Caucasian=1,Afican American=2, etc.) –

So I need to pull out these values, get the format changed, in some cases do a table-like translation (for gender and race), and write the file out in the new format.

I am limited to XSLT 1.0

I am very new to XSLT and so any help would be greatly appreciated!!!

thanks!

Thank you for the feedback and suggestions.

This version handles case conversion/comparison as well as formatting the bday in a format that I needed.

I like the AVT syntax to simplify the code and the to remove the “manual formatting” that I was doing – thanks for those tips!
