xsd - How to define a Flat file schema for a record with a repeating sequence? -
i have positional flat file contains records repeating sequence, this;
token name label value label value label value label value .. the token identifies type of record, name name value, , label (10 positions) , value (50 positions) pairs can repeat not-fixed number of times (1..*).
i have defined flat file schema below; contains (1..*), label , value correct positional data:
both label , value have minoccurs , maxoccurs of 1.
the problem have biztalk not seam able handle situation. when generate (native) instance schema following output:
token name label value (it generates single instance of label value).
when try read file has multiple occurrences of label value pairs (5), gives me following xml:
<file xmlns="http://schemas.demo/2015/01"> <repeatingrecord xmlns=""> <name>name</name> <label>label</label> <label>value</label> <label>label</label> <label>value</label> <label>label</label> <label>value</label> <label>label</label> <label>value</label> <label>label</label> <label>value</label> </repeatingrecord> </file> so label tags, no value tags. contents of value parts placed wrongly in label tag.
i expect following xml:
<file xmlns="http://schemas.demo/2015/01"> <repeatingrecord xmlns=""> <name>name</name> <label>label</label> <value>value</value> <label>label</label> <value>value</value> <label>label</label> <value>value</value> <label>label</label> <value>value</value> <label>label</label> <value>value</value> </repeatingrecord> </file> how can define flat file schema repeating sequence in record?
i have following schema:

token.name........label.....value.............................................label.....value.............................................label.....value.............................................label.....value.............................................label.....value............................................. update
what did not mention in question (for sake of simplicity) record used in flat file multiple kinds of different records, splitting record child-records not viable solution.
i able validate input top of post following, gets ont right track:
