I have two namespaces in my HTML that are conflicting with my XML schema

megelinic · August 3, 2024, 2:16pm

Here is my HTML

<html xmlns="http://www.TedTheSpeedlearner.com" xmlns:svg="http://www.w3.org/2000/svg" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.TedTheSpeedlearner.com SVG_Bezier_Curve_Webpage_XML_Schema.xsd">
    <head>
         <title>SVG_Bezier_Curve</title>
         <link rel="stylesheet" type="text/css" href="http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Bezier_Curve.css"/>
         <script language="javascript" src="http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Bezier_Curve_2.js">
         </script>
    </head>
    <body onload="Setup()">
         <input type="button" id="Bezier_Curve_Button" value="Click Me!" onclick="Setup2()"/>
         <svg:svg id="My_SVG" height="500" width="500">
         <svg:path id="Bezier_Curve_1"/>
         <svg:path id="Bezier_Curve_2"/>
         </svg:svg>
    </body>
</html>

And here is my XML Schema

<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:svg = "http://www.TedTheSpeedlearner.com"  xmlns:target="http://www.TedTheSpeedlearner.com" targetNamespace="http://www.TedTheSpeedlearner.com" elementFormDefault="qualified">

            <element name="title" type="string"/>

            </sequence>
            <attribute name="id" type="string"/>

    </complexType>
    <element name="html" type="target:HeadType"/>
</schema>

As you can see, because I have my SVG in a different namespace, I have these errors.

I don’t know what the errors are referring to, so I could use your assistance.

m_hutley · August 4, 2024, 10:19pm

If I had to guess…
The first error is complaining because it expected the <script> tag on line 5 to be a single, closed tag, but it found text content (in the form of a line break and some tabs/spaces) between the open and close tags instead.

The second error is complaining because your BodyType tells your schema to expect an SVG element that is of type: target:SvgType, where target is "http://www.TedTheSpeedlearner.com" (from your target declaration at the start).
What is actually in the HTML is an SVG element that is from a different schema.

megelinic · August 5, 2024, 4:04am

I wasn’t aware of the spaces between the opening and closing script tags. I did as you suggested and removed the spaces.

I overlooked the fact that xmlns:target was declaring a namespace. So i created a xmlns:svg and declared the appropriate SVG namespace.

But I still have one more problem. I decided to track down all my errors by simplifying my XML schema. Here is my current HTML:

<html xmlns="http://www.w3.org/1999/xhtml"
      xml:lang = "en" xmlns:svg="http://www.w3.org/2000/svg"
      xmlns:xs="http://www.TedTheSpeedlearner.com"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.TedTheSpeedlearner.com SVG_Bezier_Curve_Webpage_XML_Schema.xsd">
    <head>
         <title>SVG_Bezier_Curve</title>
         <link rel="stylesheet" type="text/css" href="http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Bezier_Curve.css"/>
         <script language="javascript" src="http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Bezier_Curve_2.js"/>
    </head>
    <body onload="Setup()">
         <input type="button" id="Bezier_Curve_Button" value="Click Me!" onclick="Setup2()"/>
         <svg:svg id="My_SVG" height="500" width="500">
         <svg:path id="Bezier_Curve_1"/>
         <svg:path id="Bezier_Curve_2"/>
         </svg:svg>
    </body>
</html>

And here is my current XML Schema:


<schema xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:schema = "http://www.w3.org/2001/XMLSchema"
xmlns:xs = "http://www.TedTheSpeedlearner.com"
xmlns:body="http://www.w3.org/1999/xhtml"
xmlns:target="http://www.w3.org/1999/xhtml"
xmlns:svg = "http://www.w3.org/2000/svg"
targetNamespace="http://www.w3.org/1999/xhtml"
elementFormDefault="qualified">
     <complexType name="HeadType">
     <sequence>
        <element name="head" type="target:TitleType"/>
        <element name="body" type="svg:BodyType"/>
     </sequence>
     </complexType>
     <element name="html" type="target:HeadType"/>
</schema>

And here is my latest error:

Any assistance would be greatly appreciated.

m_hutley · August 5, 2024, 10:27am

More guessing on my part. (I should point out i’m not an XML expert)

Well the XSD isnt valid, for starters.

Undefined type: target:TitleType (At least, I cant find anything labelled TitleType in the XHTML schema?)
Undefined type: svg:BodyType (Pretty sure the SVG schema doesnt define the HTML Body element.)

The error is saying html is undefined. Your HTML says its default namespace is http://www.w3.org/1999/xhtml. Which is a little weird because you’d think the xhtml namespace should contain a definition for an html element, but I suspect is still not your intention to use…

would you please give a try to this schema

I tried your solution but nothing worked. I also tried to simplify my xml schema in an attempt to locate the error. Here is what I tried:

<web:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns:web = "http://www.TedTheSpeedlearner.com"
           xmlns:target="http://www.TedTheSpeedlearner.com"
           targetNamespace="http://www.TedTheSpeedlearner.com"
           elementFormDefault="qualified">
    <web:element name="html" type="target:HeadType"/>
</web:schema>

I tried different namespaces as well as no namespaces at all. And I still receive the same error.

I don’t know what to do next.

megelinic · August 6, 2024, 4:13pm

In order to fix most of the problems I had on my schema, I had to change the schema location. Here is my current HTML:

<?xml version="1.0" encoding="utf-8"?>
<xs:html xmlns="http://www.w3.org/1999/xhtml"
         xmlns:svg="http://www.w3.org/2000/svg"
         xmlns:xs="http://www.w3.org/1999/xhtml"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://www.w3.org/1999/xhtml SVG_Bezier_Curve_Webpage_XML_Schema.xsd">
    <head>
         <title>SVG_Bezier_Curve</title>
         <link rel="stylesheet" type="text/css" href="http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Bezier_Curve.css"/>
         <script language="javascript" src="http://localhost:8080/exist/rest/db/apps/HTML_Student/SVG_Bezier_Curve_2.js"/>
    </head>
    <body onload="Setup()">
         <input type="button" id="Bezier_Curve_Button" value="Click Me!" onclick="Setup2()"/>
         <svg:svg id="My_SVG" height="500" width="500">
         <svg:path id="Bezier_Curve_1"/>
         <svg:path id="Bezier_Curve_2"/>
         </svg:svg>
    </body>
</xs:html>
```.
I will give everyone a second reply because of the restrictions on this platform.

And here is the final error that I’m receiving:

I’m not sure what this error code means, but I know it has to do with adding a second namespace to my HTML. I hope someone here can assist me with this.
