Scenario Imagine a scenario where I work for a financial company that deals with very large amounts of data.
Cell can be any type e. Overview[ edit ] Virtually all the core benefits of VTD-XML are inherent to non-extractive, document-centric parsing which provides these characteristics: Get all the book children of the root element and loop over them.
This section of the tutorial exposes the internal structure of a DOM, so that you can see what it contains. To accomplish the scenario we will need to take the following actions: To support the analysts' needs, the company needs to create and update Excel spreadsheets every morning.
Handling Validation Errors The default response to a validation error, as dictated by the SAX standard, is to do nothing.
For example, it can be built on a relational, hierarchical, or object-oriented database, or use a proprietary storage format such as indexed, compressed files.
If you specify an invalid combination of options, the factory generates a ParserConfigurationException when you attempt to obtain a parser instance.
Error and Exception If you happen to use incorrect classes e. This is where we read or write data. Since VTDs refer to document elements by their offsets, changes to the length of elements occurring earlier in a document require adjustments to VTDs referring to all later elements.
It is basically the same code as was used at the start of the Document Object Model lesson.
We would like to show detailed information for each book, such as would be available in a book catalog. DB mailing list, a native XML database is one that: Cell represent a block in Excel, also known as cell.

Several other W3C specifications are also critical to the understanding and implementation of XML as it. Reading XML Data into a DOM In this section, you will construct a Document Object Model by reading in an existing XML file.
Note - In Extensible Stylesheet Language Transformations, you will see how to write out a DOM as an XML file.
Makes writing XML much much easier Use DOM L3 DOMBuilder, DOMBuilderFilter DOMWriter and other DOM L3 functionality to preparse, revalidate and safe document.
