Last week, we presented a simple framework (named XMLCast) for distributing content to a variety of devices using XML. This application was built using Microsoft's Active Server Pages (ASP) technology but we realize that many of you aren't using ASP (we aren't either). This article will present the concept of XML parsing using the PHP scripting language. In the coming weeks, we will follow this example up with an expansion of XMLCast using other tools such as XSLT and Cocoon.Recently, The Wireless Developer Network began offering our daily news in a variety of formats for people that wanted their news delivered in ways other than standard HTML. Among the formats we offer is Rich Site Summary (RSS), an XML format that splits up items (news headlines, in this case) into easily extractable elements, allowing other sites to grab our latest news headlines, format them as they wish, and list them on a page on their site, all with the convinence of XML data exchange.

It’s old news, but for those who’ve been living in a cave, Google has a search API (launched back in the summer of 2002), that you can access via any programming language to add search functionality to your web apps. Long back, I decided to build a PHP application for that, and for those who wanna have some fun with it, and learn some web services api programming with php et. al. I’ve put down an article along with a sample app and some scripts that you can download and tweak to your heart’s content.

A markup language is a collection of directions and special symbols that are inserted throughout a document. These directions can identify special sections of a document and further define the information's background and meaning.A commonly used markup language on the Internet today is Hyper Text Markup Language (HTML). HTML directions (which are known as elements) are interspersed throughout a text file that can then be viewed by a web browser program. The elements can affect the formatting of text, break the document up into logical sections such as headers, paragraphs and lists and can even link several documents together.

In one of my previous tutorials, Processing XML with PHP, I introduced you to the expat XML parser. The parser is sufficient for extracting information from an XML document and manipulating it in a simple event based manner. However, there may be times when it's desired to transform the XML document into a different format using XML StyLesheet Transforms (XSLT). XSLT is essentially a series of templates and rules for XML. It processes a document by applying the template patterns according to the prescribed rules. XSLT can be used to generate pretty much any type of file from an XML document, such as .svg, .cvs, or .pdf. In this tutorial we will use XSLT to transform an XML document into an HTML document and use PHP?s XSLT functions to apply those rules.

I will be the first to admit that I love computing standards. If every vendor adhered to an industry standard, I think the web would be a better medium for everyone. Using standardized data exchange formats, open, platform-independent computing models become feasible. It is for this reason that I am a big fan of XML.Fortunately for me, my favorite scripting language supports XML and is continuing to strengthen this support. PHP has enabled me to quickly bring XML documents to the web, to gather statistical information about them, and to transform them to other formats. For example, I regularly use PHP's XML processing capabilities to manage my articles and books written using XML.

Scripting languages have been in use for years to make function calls and to integrate disparate applications. A little bit of script glue can make applications from different vendors talk to each other and exchange information.

This is a quick tutorial that shows you along with an example script how to grab remote RSS/RDF XML news files and parse them so you can display news headlines from any site that has an RSS/RDF file - most of the bigger sites do. You can also learn the standard format for creating your own Valid RDF files. Uses FileSystem and regular expression functions.
