| Using XPath with PHP
If your PHP applications perform beyond CRUD operations, chances are you have
worked with XML. Navigating an XML document or data stream for the desired data
elements can be cumbersome, though, and even somewhat intimidating for PHP developers. It can be especially overwhelming when the XML data structure is complex. XPath is a W3C standard whose sole purpose is just that -- getting to the right data element, or, specifically, the desired node. PHP supports XPath as part of its XML classes and functions. In this article you explore some basic scenarios for locating information in XML and how XPath can do the hard work for you in your PHP applications.

find themselves using a taxonomy that divides the problem-space using three levels. For example, in a financial application, a ledger record might be identified categorically (debit or credit) and then broken down within these categories by type and subtype (for instance, "interest accrued due to prior underpayment" might be broken into a triple of credit/interest/underpayment). You can model this sort of structure in XML in a number of ways depending on the requirements of the data, and you can enforce this modeling using a variety of different schema approaches. I describe two schema approaches: W3C XML Schema Definition (XSD) and Organization for the Advancement of Structured Information Standards (OASIS) Content Assembly Mechanism (CAM).

| Tip: Transforming XHTML using XSLT identity templates
XHTML isn't just well-formed HTML: Certain tags must be properly closed. Improperly closed tags are valid XML, but browsers might incorrectly parse them, causing problems with dynamic Web 2.0 features. Whether transforming XML to XHTML or just filtering XHTML, discover the XSLT templates you need to create correct XHTML that follows W3C-recommended practices for XHTML.

| Tools and XML functionality for DB2 pureXML users
This article provides guidance to database users in choosing XML tools to help them
with the new responsibilities that arise now that IBM DB2 can efficiently store and manipulate XML data with
pureXML. The size of XML, which can vary from a few kilobytes (KB) to many megabytes (MB) per document
instance, and the hierarchical structure creates the need for new tool capabilities to ease the tasks of
creating, viewing, editing, and querying XML instances and schemas when using DB2 pureXML. This article reviews
the XML capabilities in tools available from IBM for working with XML database objects,
the different job roles that are impacted by having XML in the database, and the specific tasks involved. It then
describes the key XML-related tasks that arise and outlines which tools provide capabilities to help with those
tasks.

| Using CICS with DB2 pureXML, Part 2: Perform advanced XML storage and retrieval through CICS Web services
This article is the second part of a series of articles. The first article focused
on augmenting CICS(R) Web services with two general purpose routines (pipeline handlers)
that support two scenarios to store and retrieve XML in DB2(R) pureXML. This second part
introduces two more scenarios: a service request scenario and a service response
scenario. The service request scenario shows how a custom pipeline handler can be
introduced to further enhance CICS Web services to store XML
data in relational form or in XML form after extracting the XML that represents the business data from the SOAP message.
The service response scenario shows how a custom pipeline handler can be introduced to publish relational data as XML, and how XML
data can be modified directly through SQL before returning the data in a service response.
This article also illustrates how stored XML data can be accessed as relational data through a view for easy placement in a CICS COMMAREA or
container. Some sample COBOL source code is included in the Downloads section.

| Representing predictive solutions in PMML
PMML, the Predictive Model Markup Language, is the de facto standard used to represent a myriad of predictive modeling techniques, such as Association Rules, Cluster Models, Neural Networks, and Decision Trees. These techniques empower companies around the globe to extract hidden patterns from data and use them to forecast behavior. In this article, start with a look at the predictive modeling techniques that are directly supported by the standard. However, given that a predictive solution is more than the statistical techniques it harbors, then dive even deeper into the language and explore the transformations and functions that are used for data processing by illustrating the use of data pre-processing and modeling in PMML as it is used to represent a complete predictive solution.
