XML - eXtensible Markup Language (by W3C), similar to HTML,
in which tags may be defined by the users, or standard tags defined for, say, a particular industry
(see XSL). Opening and closing tags
<TAG> ... ... </TAG> must match, and nest without overlapping. XML code can be embedded
in HTML between <XML> ... ... </XML> - see datasrc=.
To get troublesome items from the XML file, do e.g.
<PUBLISHER>
<![CDATA[ <A HREF="http://www.microsoft.com/mspress/">Microsoft Press</A> ]]>
</PUBLISHER>
and in the HTML file:
<TD><SPAN datafld="PUBLISHER" dataformatas="HTML"></SPAN></TD>
- see mjy Online - XML Tips
Data can also be extracted using the recordset attribute. e.g.
XmlXxx.recordset( "Yyy" ).value
or
var recOptions = entmvStyle.recordset;
x = recOptions( "font-family" );
N.B. The default character set (UTF-8 - an 8-bit encoding of the Unicode character set) prohibits accented characters.
Instead, use ISO-8859-1 (also called Latin 1), which is the most common Western encoding in use on the Web.
It matches the default character set used on Windows in most Western countries.
It does not match the character set used in most non-Western countries, or in most Western versions of the Mac OS (MacRoman).
The first 127 characters (binary codes 1-127) are the same in most countries.
Some other character sets are:
US-ASCII - supports only 7-bit characters.
EUC-JP - used widely in Japan.
SHIFT_JIS - also used widely in Japan - default in Japanese versions of both Windows and the Mac OS.
UTF-16 - a 16-bit encoding of the Unicode character set

XMLDOM - see DOM.
XMLHTTP object - can be used to get data from Internet Server which is not a complete new page.
Not necessarily anything to do with XML,
though there is a method (.responseXML) for sending XML to the server).
Microsoft access the object with:
new ActiveXObject( "Microsoft.XMLHTTP" )
and Mozillawith:
new XMLHttpRequest()
Thereafter the methods are the same, though Mozilla seem to have an onload event which is similar
to onreadystatechange.
The open method can use GET, POST, or PUT (see HTTP
and w3 HTTP spec: Method Definitions).
For this and other methods, see (msdn):
open

XPath XML Path Language - node selection and manipulation used in XSLT.
See XPath v1.0 W3C spec and XPath Tutorial.
Addressing Infosets with XPath MSDN jul00: The XML Files
XSL - eXtensible Stylesheet Language defines how to process and display an XML
document. Allows for rearranging, deleting, and inserting document content, which makes it better than HTML
Cascading Style Sheets, but not by much.
Can contain HTML constructions, but since XSL documents are also XML
documents, every element must have a matching terminator element
e.g.
<INPUT . . .> </INPUT>
or be self terminating, e.g.
<BR/>
See
The Tao of Recursion: Named Templates in XSLT for good introduction (by DevX).
See latest (?) XSL draft spec.
- A URI similar to the one for the above ("http://www.w3.org/TR/WD-xsl")
must be put into the xsl:stylesheet element of every XSL file. e.g. the .xsl file structure is:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/TR/WD-xsl">
. . .
</xsl:stylesheet>
- the URI is just a constant like a version number. The WD in the above stands for "Working Draft",
so perhaps there is a more up-to-date one.
- See Using Namespaces in XSL for more on this riveting topic.
- The system does check this value, and probably no data will be displayed if it is not valid.
- The ns in xmlns stands for "namespace", which is a term beloved by the spec writers,
and the xsl which follows is a "shorthand" name for the URI thing that follows that,
and which is used with more convenience in the rest of the document.
The first impression is that XSL is just DOM with restrictions.
- For instance, it seems very difficult to use data from the XML file as parameters to functions.
Also see spec on messing with the XML document structure.
