Chances are, you won't find a module that specifically addresses your needs. You'll more likely take one of the general XML modules and adapt it somehow. We'll show that this process is painless and reveal several ways to configure general modules to your particular application. XML parsers differ from one another in two major ways. First, they differ in their parsing style , which is how the parser works with XML. There are a few different strategies, such as building a data structure or creating an event stream.
When you query a database, you're usually looking for only a single record. When you crack open a telephone book, you're not going to sit down and read the whole thing. There is obviously a need for some mechanism of extracting a specific piece of information from a vast document. Look no further than XPath. 20 It's a grammar for writing expressions that pinpoint specific pieces of documents. Think of it as an addressing scheme. Although we'll save the nitty-gritty of XPath wrangling for Chapter 8, we can tantalize you by revealing that it works much like a mix of regular expressions with Unix-style file paths.
In practice, a Schematron document looks and feels like an XSLT stylesheet, and with good reason: it's intended to be fully implementable by way of XSLT. In fact, two of the XML::Schematron Perl modules work by first transforming the user-specified schema document into an XSLT sheet, which it then simply passes through an XSLT processor. Schematron lacks any kind of built-in data typing, so you can't, for example, do a one-word check to insist that an attribute conforms to the W3C date format. You can, however, have your Perl program make a separate step using any method you'd like (perhaps through the XML::XPath module) to come through date attributes and run a good old Perl regular expression on them.
