Beginning XML: Where and how can I get the XML programming started?

ScottChang · March 24th, 2015, 10:37 AM

Hi all,
I bought a copy of the Book "Beginning XML 2nd Edition" written by David Hunter, et. al. (published by Wrox) many years ago. I learned the basic stuff of XML, DTD and DOM before. Recently, I reviewed the book and wanted to do my XMY programming again. Now I am very rusty in doing XML programming. I try to do my first XML Schema by using the name5.xsd
CODE]<?xml version="1.0"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema""
targetNamespace="http://www.wrox.com/name" xmlns:target="http://www.wrox.com/name"
elementFormDefault="qualified">
<element name="name">
<complexType>
<sequence>
<element name="first" type="string"/>
<element name="middle" type="string"/>
<element name="last" type="string"/>
</sequence>
</complexType>
</element>
</schema>
[/CODE]

and name5.xml:

Code:

<?xml version="1.0"?>
<name
  xmlns=http://www.wrox.com/name"
  xmlns:xsi="http://www.wrox.org/2001XMLSchema-instance"
  xsi:schemaLocation="http://www.wrox.com/name name5.xsd"
  title="Mr.">
    <first>John</first>
    <middle>Frizgerald</middle>
    <last>Doe</last>
</name>

Where and how can I execute these 2 files (name5.xsd and name5.xml)?

Please kindly help and advise me where and how I can get the xml programming Started and have the name5.xsd and name5.xml executed.

Thanks in advance,
Scott Chang

Good evening.

I tried to combine XHTML with SVG. It worked fine until I started adding namespaces. After much searching, I found something called Namespace-based Validation Dispatching Language (NVDL). Has anyone ever heard of this? Can it be used in conjunction with the eXist database program?

>Has anyone ever heard of this?

Yes. But without knowing your problem (beyond the fact that "it doesn't work fine"), it is impossible to know whether NVDL is the answer.

>Can it be used in conjunction with the eXist database program?

All XML technologies can be used "in conjunction with" each other if you try hard enough, but I don't know if there is any close integration.

This is my HTML document:

<html>
<head>
<title>SVG Ellipse</title>
<link rel = "stylesheet" type = "text/css" href = "SVG_Ellipse.css">
</link>
<script language = "javascript" src = "SVG_Ellipse_Test_1.js">
</script>
</head>
<body onload = "Setup()">
<svg id = "Image_Box">
<ellipse id = "My_Ellipse">
</ellipse>
</svg>
<input id = "My_Data" type = "text">
</input>
</body>
</html>

When I open this document, everything works fine. But when I change this to an XHTML document and add namespaces for the XHTML and the SVG, it stops working. Let me show you:

<?xml version = "1.0" encoding = "UTF-8" standalone = "no"?>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:svg="http://www.w3.org/2000/svg" >
<head>
<title>SVG Ellipse</title>
<link rel="stylesheet" type="text/css" href="http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Ellipse.css"/>
<script language="javascript" type = "text/javascript"src="http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Ellipse_Test_2.js"/>
</head>
<body onload="Setup()">
<svg:svg id="Image_Box">
<svg:ellipse id="My_Ellipse"/>
</svg:svg>
<input id="My_Data" type="text">
</input>
</body>
</html>

I was hoping the Namespace-based Validation Dispatching Language would bridge the missing gap. If so, how would this work with the eXist database?

You say "it stops working". What is "it" (ie. what are you doing with the document? You say you're opening it, but with what? A browser? Which browser?), and how exactly does it fail?

speedlearner1 · September 7th, 2015, 01:03 PM

I've tried to open this document in Google Chrome and in Firefox. The textbox appears, but the SVG Ellipse won't.

Does this help: http://stackoverflow.com/questions/2...html-documents

For a true XHTML file you may be missing the DocType declaration perhaps?

speedlearner1 · September 8th, 2015, 09:16 AM

No it doesn't. I have a feeling that I will have to save one copy of my document in regular html so it will work and another copy in xml so I can validate it. I think this is a stupid solution and I think someone should create an alternate solution to this problem.

How do you open the document in the browser, do you open it from the file system or do you load it from a HTTP server? If you want to use XML from thefile system then you need to make sure you use a suffix like .xml or .xhtml, otherwise the browser will not use its XML parser. If loaded from a HTTP server the document needs to be served as text/xml or application/xml or application/xhtml+xml.
