References - XML Roundtable - DVCUG Feb 21, 2001
www.axs2000.net/jvoris will have materials and links on site
Samples, useful stuff and contacts
(Things you may not have seen)
Microsoft's XML Notepad Editor may be a useful tool
Remember that IE 5.x & Navigator 6.x are XML enabled (It understands the syntax and formatting) Sample of using the parser within IE5 is at www.VBXML.com
Has anyone here tried some XML ?
Some good references as well as www.ibm.com/developer

Conference: February 27 to March 2 5 tracks, 70 sessions, 2500 attendees

Only the exhibit floor is free (Thurs, 3/1 12:45 - 6:45 and Fri, 3/2 12:00 - 5:00),
but they do have night school sessions and a course for getting SUN Java Certified.

Examples in RPG
Source for the RPG XML settings uses lots of Sub-Procedures and Pointers
It is true ILE with SRVPGM *MODULES and the CRTPGM command
Laptop has source for SAXCOUNT and RPGBD2SAMP
Setting up the samples:
They are hardcoded to by folder name on the IFS!
Within Ops Navigator, create the folder under ROOT! So it will look like
ROOT / XML4PR310
Put a SHARE on the folder
Don't have to make it a converted folder. Do you know what a converted folder is - it is great for CPYFRMSTMF for EBCDIC-ASCII conversion on the fly.
You need not be familiar with FTP - follow instructions and it installs nicely.
But I believe that this XML / RPG wrapper will only be used by product vendors
What the future will really be….. DAD Document Access Definitions
Redbook SG246130 XML Extenders to compose XML from relational data or decompose
This is a GUI Tool for DB2 UDB ! DAD's are coming in the next release of IBM !
DB Text Extender allows structural search and full text search into an XML document.
Page 193/213 of .PDF has a has Servlets (like BrowseOrderServlet) which is well documented.
Summary of this presentation
The RPG samples use both SAX and DOM parsers. SAX is simple, fast, beginning to end parser. DOM puts the document into memory and can be manipulated.
Other Parsers are coming: XML for Java (XML4J) JSAX
Get familiar with some more terms, and concepts:
XPATH - A query language for nodes
VML Vector Markup Language
And the following quote from XML Magazine:
If you are familiar with Cascading Style Sheets, you may think that an XSL style sheet is simply a different way of expressing styles. It isn't. XSL is a technology written in XML that can associate given element patterns in an XML document with other collections of strings (or better yet, with elements from a different XML form). XSL can take an XML document as input and convert it into HTML, for example. However, if that HTML document isn't also an XML document, then most XSL parsers have to manipulate the HTML as strings, which is much less efficient than manipulating the element as internal binary objects.
Moreover, XSL can't transform HTML into XML unless the HTML is also well-formed XML. On the other hand, with XHTML you can perform a direct transformation into another XML structure (or even into different XHTML), pass an XHTML document through but change only a few selected elements, or retrieve information that may be contained in an HTML table and convert it into a different XML structure.
For example, you could create a relatively simple XSL transform that would read through an XHTML document and convert any expressions of the form <clock:showTime format="long"/> into the expression <span class= "clock">3:25:16 PM PST</span> when displayed. This gives you the capability of creating a tag-based system ofoutput similar to Allaire's Cold Fusion, but one in which you could explicitly define all of the actions that you wanted to perform
