So I'm trying to understand the basics... If I put an xml file and an xsl file in a folder together with the xml file containing a path to the xsl file, shouldn't this work sort of like an HTML file and CSS file? I was expecting a rendered output similar to the output you get in the "XSLT Tryit" editor here: http://www.w3schools...tfile=cdcatalog 

<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type="xsl" href="myxslfile.xsl"?><!DOCTYPE Artist [etc...

But it doesn't work. The browser does not format it. Using type="text/xsl" does not fix it. The same pair of files can be pasted into the "XSLT Tryit" page and there they produce a formatted result.

The type should be "text/xsl"With the information you've provided, I can't see how it wouldn't work. You'll have to post all the code, or show an example online.

Oh, it apparently didn't like my filename. Also it didn't like n b s p being in there. I need n b s p although I guess I can add padding/margin or something. What is the best approach for spacing out displayed elements? & n b s p ; didn't work but & # 160 ; works. I'm happy. -- edit Hmmm. Maybe I'm not happy. So DTD's are obsolete? Do I just replace the DTD with a Schema or do I need to keep that separate and have another header path statement such as... 

<?xml version="1.0" encoding="ISO-8859-1"?><ArtistListxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="myxmlschema.xsd">

Also in the xsl stylesheet, how do I print an attribute?

yes.

With "@" in front of the node name.

Ok, thanks! I'm still having trouble with namespaces or paths or something. Why do namespaces need a URI and what is the meaning of the URI? Does it look for the file at the location of the URI path? I have three files in the same folder... but it isn't working. I think the XSD, the XSD reference, or the XSD namespace is the problem. The same XSL file works fine when I use a DTD. If I change the order of the two references in the top of the XML file I can either see the data or the formatting, but not both. prob12.34d.xml file:

<?xml version="1.0" encoding="utf-8"?><ArtistListxmlns="http://www.w3schools.com"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.w3schools.com prob12.34d.xsd"><?xml-stylesheet type="text/xsl" href="prob12.34d.xsl"?><Artist ArtistID="1">  <ArtistName>	<FirstName>Joan</FirstName>	<LastName>Miro</LastName>  </ArtistName>	<Nationality>Spanish</Nationality>	<DateOfBirth>1893</DateOfBirth>	<DateDeceased>1983</DateDeceased></Artist><Artist ArtistID="2">  <ArtistName>	<FirstName>Wassily</FirstName>	<LastName>Kandinsky</LastName>  </ArtistName>	<Nationality>Russian</Nationality>	<DateOfBirth>1866</DateOfBirth>	<DateDeceased>1944</DateDeceased></Artist></ArtistList>

prob12.34d.xsd file:

<?xml version="1.0" encoding="utf-8"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"elementFormDefault="qualified"attributeFormDefault="unqualified"> <xs:element name="ArtistList"><xs:annotation>  <xs:documentation>???</xs:documentation></xs:annotation><xs:complexType><xs:sequence>  <xs:element name="Artist">  <xs:complexType>  <xs:sequence>	<xs:element name="ArtistName">	<xs:complexType>	<xs:sequence>	  <xs:element name="FirstName" type="xs:string"/>	  <xs:element name="LastName" type="xs:string"/>	</xs:sequence>	</xs:complexType>	</xs:element>	<xs:element name="Nationality" type="xs:string"/>	<xs:element name="DateOfBirth" type="xs:date"/>	<xs:element name="DateDeceased" minOccurs="0" type="xs:date"/>  </xs:sequence>  <xs:attribute name="ArtistID" type="xs:positiveInteger" use="required"/>  </xs:complexType>  </xs:element></xs:sequence></xs:complexType></xs:element></xs:schema>

prob12.34d.xsl file:

<?xml version="1.0" encoding="utf-8"?><xsl:stylesheetversion="1.0"xmlns:xsl="http://www.w3.org/1999/XSL/Transform"xmlns:fo="http://www.w3.org/1999/XSL/Format"> <xsl:output method="html"/> <xsl:template match="/"><html><head><title>Artists List</title><style type="text/css">body {background-color: gray;}.cname {font-size: 14pt;color: black;background-color: blue;font-weight: bold;padding: 5px;}.cyears {font-size: 10pt;font-style: italic;color: black;}.cdetail {font-size: 10pt;color: green;background-color: white;padding-left: 15px;}</style></head><body><h1>Artist List</h1><hr/><xsl:for-each select="ArtistList/Artist"><div class="cname"><xsl:value-of select="@ArtistID"/>:  <xsl:value-of select="ArtistName/FirstName"/><xsl:value-of select="ArtistName/LastName"/>  <span class="cyears">(Born:<xsl:value-of select="DateOfBirth"/>Died:<xsl:value-of select="DateDeceased"/>)</span></div><div class="cdetail">Nationality:<xsl:value-of select="Nationality"/></div><hr/></xsl:for-each> </body></html></xsl:template></xsl:stylesheet>

No difference in using either of the following...

<ArtistListxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="prob12.34d.xsd">

or

<ArtistListxmlns="http://www.w3schools.com"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.w3schools.com prob12.34d.xsd">

The proper order is to have the PI ("Processing Instruction"; the "<?" thingy) before the root element.Also, for a validator to recognize your declarations, the namespaces everywhere need to match. In this case, your elements are not in a namespace, so the "noNamespaceSchemaLocation" is the proper attribute to use, i.e.

<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type="text/xsl" href="prob12.34d.xsl"?><ArtistListxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="prob12.34d.xsd">

You're not supposed to see both the data and the formatted HTML... The PI is used exactly to tell the browser to hide the data in favor of whatever the result of the XSLT transformation is (which in your case is an HTML page, but could be an SVG instead for example).Also, no browser does either DTD or Schema validation, so you're not going to get any schema related errors in a browser. For that, you'd need to use the server. e.g. PHP's DOMDocument::schemaValidate() which, as you might be guessing, ignores your XML declaration too. So what's the point of that declaration you ask? IDEs - they can offer you auto completion based on the declared schema, and some can even validate your document "on the fly", and tell you an element is invalid at that location as soon as you write it out.

Oh heck, it did work. I must not have tried the noNamespaceSchemaLocation in this order... 

<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type="text/xsl" href="prob12.34d.xsl"?><ArtistListxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:noNamespaceSchemaLocation="prob12.34d.xsd">

Thanks! But now what is the match-up that is needed for the use of a namespace? I obviously had it wrong taking headers right from the examples here: http://www.w3schools...hema_schema.asp How would I need to modify the earlier files posted above to fix the namespace problem? Thanks. This does not work...

<?xml version="1.0" encoding="utf-8"?><?xml-stylesheet type="text/xsl" href="prob12.34d.xsl"?> <ArtistListxmlns="http://www.w3schools.com"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.w3schools.com prob12.34d.xsd"> <Artist ArtistID="1">  <ArtistName>	    <FirstName>Joan</FirstName>	    <LastName>Miro</LastName>  </ArtistName>	    <Nationality>Spanish</Nationality>	    <DateOfBirth>1893</DateOfBirth>	    <DateDeceased>1983</DateDeceased></Artist><Artist ArtistID="2">  <ArtistName>	    <FirstName>Wassily</FirstName>	    <LastName>Kandinsky</LastName>  </ArtistName>	    <Nationality>Russian</Nationality>	    <DateOfBirth>1866</DateOfBirth>	    <DateDeceased>1944</DateDeceased></Artist></ArtistList>
