New screen-cast on the Split-OpenXmlDocument cmdlet in PowerTools for Open XML
In document processing parlance, shredding a document is the process of dividing a source document according to certain rules, and creating a number of documents from the source document. This is useful, for instance, when you have a huge document, and you want to divide it into multiple documents to hand off to different authors or editors. Then, after all edits have been completed, you can merge the various parts back into a complete document.
Shredding a document has much in common with DocumentBuilder. The process of identifying specific subsections of a document and creating new documents from those sections involves the same issues of identifying interrelated markup, and creating the new document with just those resources necessary for the specific subset of the original document.
The following screen-cast shows how to use the Split-OpenXmlDocument cmdlet to shred a document based on sections. It then shows merging those separate documents back into a single document using the Merge-OpenXmlDocument cmdlet.
