? Structure pattern
Help on Structure Pattern :
The purpose of this indicator is to reveal what the Xml stream is most made of. So far, no one tool in the software industry has such an approach to an Xml structure. Inspecting patterns is a key process in order to understand why an Xml stream is so large in size.
Additionally to the structure, this indicator infers data types associated to elements and attributes. Among recognized data types are : float numbers, integral numbers, currencies, dates, urls and emails. An element or attribute with no associated data type is a pure character string with no particular data type inside. Again the process of automatically extracting data types helps a lot in order to for instance : propose a replacement for a date data type if it has unnecessary time fields thus large in size, validate content against a known data type, facilitate Xml transforms (automatic mapping).
Hint : because the pattern is what the Xml stream is most made of, a special attention should be paid so it keeps the lowest profile in terms of size. It is straight forward that the smaller in size the pattern is, the smaller in size is the Xml stream.
Below is a full Xml document sample along with its extracted pattern.
