Datel XML Transliterator
Pure python 99.9% losless transformations of XML to python dicts, JSON, or JSON Lines.
Datel Data Element and Record Scheme
Input XML with your records and an XPath pointing to the root element of records to extract.
The first step is to apply the XPath to the XML Document, iterating over each record.
For each record, the next step is to iterate over each record node, creating an array for each record containing Datel Data Elements. Then, the datel elements are merged into one dict per record.
The command outputs JSON Lines.
The default format creates one dict per record, supplying the flag
--no-solsource will enabling an order-preserving mode with one
dict per XML Element in the source.

pydoc datel
