XML and XPath in the Wild
This talk outlines our team’s findings on the properties of XML documents and XPath expressions “in the wild”.
As part of an ongoing effort to develop XML processing hardware and software, our team has collected thousands of samples of various XML species from the web to analyze in our lab. Dissecting these critters with various statistical tools, we developed a characterization of “typical” XML documents in each of some familiar species, including RSS and XTHML. Belaboring the metaphor further, we also cloned these species, taking the statistical characteristics and feeding them to a custom-designed tool for generating XML documents matching statistical profiles.
The talk with also describe a related investigation into XPath in which we extracted expressions from hundreds of open source projects. We found some illuminating patterns in XPath usage in those projects.
