I am trying to build an XSD file based on the following text file (flat file). I am using the flat file schema wizard but can't achieve what I want.
:BEGIN
Key1 Value1
Key2 Value2
:END
:BEGIN
Key1 Value1
Key2 Value2
Key3 Value3
:END
:BEGIN
:END
The XSD would be something like :
Record (Delimited by :BEGIN and :END)
|_Association (Delimited by \n)
|_Key (Delimited by space, first occurence)
|_Value (second occurence)
I would like my txt file to be transformed as an instance of the xsd file in xml. The result would be something like :
<Record>
<Association>
<Key>Key1</Key>
<Value>Value1</Value>
</Association>
<Association>
<Key>Key2</Key>
<Value>Value2</Value>
</Association>
</Record>
<Record>
<Association>
<Key>Key1</Key>
<Value>Value1</Value>
</Association>
<Association>
<Key>Key2</Key>
<Value>Value2</Value>
</Association>
<Association>
<Key>Key3</Key>
<Value>Value3</Value>
</Association>
</Record>
There is only 2 records because last :BEGIN:END block is empty.
My main issue is that I can't find out how to delimit my records by :START and :END tags. Is that even possible ?
Yes, it is possible to do, but not with the Wizard. It is a matter of manually building it up and testing the structure as you add definitions.
It is a matter of using Tag Identifiers for the :BEGIN and :END as well using a Sequence Group to say that these re-occur.
Additionally at the <Schema> level set Parser Optimization to Complexity.
Depending on what defines the end of your line, you may need to adjust the 0x0A 0x0D (Carriage Return & Line Feed) to what your file actually contains. Also if the last line does not finish with a CR/LF then change it from being Postfix (after) to Infix (between).
