I have a xml data file that looks like this
<CT_DATASET>
<DATE-INTERVENTIONDATE>
<YEARS>0</YEARS>
<MONTHS>0</MONTHS>
<DAYS>-1</DAYS>
</DATE-INTERVENTIONDATE>
<DESCTEXT>Preoperative CT Diagnosis</DESCTEXT>
<NUMBER_OF_SLICES>58</NUMBER_OF_SLICES>
<DICOM_TAGS>
<TAGNR>00080014</TAGNR>
<TAGVALUE>1.2.840.113701.4.2.102</TAGVALUE>
</DICOM_TAGS>
<DICOM_TAGS>
<TAGNR>00080016</TAGNR>
<TAGVALUE>1.2.840.10008.5.1.4.1.1.4</TAGVALUE>
</DICOM_TAGS>
<DICOM_TAGS>
<TAGNR>00080018</TAGNR>
<TAGVALUE>1.2.840.113701.4.2.102.0.2187.8.1.0.7< /TAGVALUE>
</DICOM_TAGS>
<DICOM_TAGS>
<TAGNR>00080070</TAGNR>
<TAGVALUE>Toshiba </TAGVALUE>
</DICOM_TAGS>
</CT_DATASET>
And I want to map the multiple tagnr and tagvalue to one column for the
patient.
My schema file looks liek this:
<xs:element name="CT_DATASET" sql:relation="CT_DATA"
sql:overflow-field="ADDITIONAL">
<xs:complexType>
<xs:sequence>
<xs:element ref="DATE-INTERVENTIONDATE" />
<xs:element ref="DESCTEXT" />
<xs:element ref="NUMBER_OF_SLICES" />
<xs:element minOccurs="0" maxOccurs="unbounded" ref="DICOM_TAGS" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="NUMBER_OF_SLICES" type="xs:string" />
<xs:element name="DICOM_TAGS" sql:is-constant="1">
<xs:complexType>
<xs:sequence>
<xs:element ref="TAGNR"/>
<xs:element ref="TAGVALUE"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="DATE-INTERVENTIONDATE" sql:is-constant="1">
<xs:complexType>
<xs:sequence>
<xs:element ref="YEARS" />
<xs:element ref="MONTHS" />
<xs:element ref="DAYS" />
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="DESCTEXT" type="xs:string"/>
<xs:element name="YEARS" type="xs:string" sql:field="years"/>
<xs:element name="MONTHS" type="xs:string" sql:field="months" />
<xs:element name="DAYS" type="xs:string" sql:field="days"/>
<xs:element name="TAGNR" sql:field="TAG_NO:"/>
<xs:element name="TAGVALUE" sql:field="TAG VALUE"/>
</xs:schema>
I get an error which says:
Data mapping to column 'TAG_NO' was already found in the data. Make
sure that no two schema definitions map to the same column.
Does anybody know a way around. Any help would be appreciated. Please
do help!!!
Hello Prakruthi,
Are you trying to use this as a validation schema in an XML Schema collection
or a XDR for mapping queries?

|||Hi Kent,
Im trying to use this as a validation schema. And as you can see from
the xml data , each patient has multiple dicom tags and numbers. I want
to be able to map all these numbers into a single column. Is this
possible?
|||Hi Kent,
I forgot to mention that Tag Numbers and Tag values are two separate
columns. But each column should be able to have multiple values.

Prakruthi
|||Hello Prakruthi,
Part of problem is that the schema you posted isn't a valid XSD schema:
a. The sql namespace (aliased by sql
isn't defined by your schema.b. The schema has some other problems, so I rewrote it -- sans the SQL parts
since I'm not sure what these are or do in your processor.
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:element name="CT_DATASET">
<xs:complexType>
<xs:sequence>
<xs:element name="DATE-INTERVENTIONDATE">
<xs:complexType>
<xs:sequence>
<xs:element name="YEARS" type="xs:string"/>
<xs:element name="MONTHS" type="xs:string"/>
<xs:element name="DAYS" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="DESCTEXT" type="xs:string"/>
<xs:element name="NUMBER_OF_SLICES" type="xs:string"/>
<xs:element ref="DICOM_TAGS" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="DICOM_TAGS">
<xs:complexType>
<xs:sequence>
<xs:element ref="TAGNR"/>
<xs:element ref="TAGVALUE"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="TAGNR" type="xs:string"/>
<xs:element name="TAGVALUE" type="xs:string"/>
</xs:schema>
I was able to catalog is into a SQL Sever 2005 XML Schema Collection succesfully.
Does any of that help?

|||Dear Kent,
Thanks for reorganising my schema in the right manner. But I dont think
you understood what I meant to say. Even when I used your modified
schema I could not map the three tagnr and tagvalues associated with
one one single patient into the tagnr and tagvalue column.I get an
error that says
Data mapping to column 'TAG_NO' was already found in the data. Make
sure that no two schema definitions map to the same column.
Is it not possible to map three different values to one column of the
same row? I hope you can help me out again this time.
Regards,
Prakruthi
|||Hello Prakruthi,
That's why I asked if you were using this an mapping schema or as a validation
schema. You said "validation," so I fixed it for that. However, I don't believe
you can target more than one value into a column using a single mapping.
Sadly, I don't have the time to work on this today before going on the road
for the next couple of week. However, it looks like Michael is back online,
so he might be able to help more.

Ping me if that is not the case.
