As far as I know, every xsl stylesheet requires <xsl:stylesheet> (or <xsl:transform> -- http://www.w3.org/TR/xslt#stylesheet-element) element, which contains all your transformations.

Try saving the following as "breakfast.xsl" in the same folder where you have "breakfast.xml":

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output method="html"/>
	
	<xsl:template match="/"> 
        <html>
        <body style="font-family:Arial;font-size:12pt;background-color:#EEEEEE">
        <xsl:for-each select="breakfast_menu/food">
          <div style="background-color:teal;color:white;padding:4px">
            <span style="font-weight:bold"><xsl:value-of select="name"/> - </span>
            <xsl:value-of select="price"/>
            </div>
          <div style="margin-left:20px;margin-bottom:1em;font-size:10pt">
            <p>
            <xsl:value-of select="description"/>
            <span style="font-style:italic"> (<xsl:value-of select="calories"/> calories per serving)</span>
            </p>
          </div>
        </xsl:for-each>
        </body>
        </html>
	</xsl:template>
</xsl:stylesheet>

Open in new window

To test the above xsl file directly on the browser, in breakfast.xml "link" to the xsl file above:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="breakfast.xsl"?>
<breakfast_menu>...</breakfast_menu>

Lastly, open Firefox, and open breakfast.xml

both in same folder of eclipse as attached. Do i need to refer xsl name in xml somewhere or otherway?

i wan to run in the eclipse though not in browser

Use the xsl file I posted above. Your screenshot shows the one that doesn't have the <xsl:stylesheet> element. As for the transformation, refer to:
https://docs.oracle.com/javase/tutorial/jaxp/xslt/transformingXML.html

Look on the heading "Writing the Basic Program"

My code on other laptop has below
<xsl:template match=
But it does not have below
<h2> <xsl:apply-templates
what is the difference between these two. when to use which one and why we need templates in XSL.
I am also reading that link which is good.
please advise

hielo

You are not obligated to create templates for your nodes -- ex: <xsl:template match="food">...</xsl:template>. You can do all the processing in the "starting/entry" template ( in the example you posted, this is <xsl:template match="/">...</xsl:template> -- if you are familiar with c/c++, think of it a main). However, the advantage of templates is that they simplify the processing logic significantly.

If you are completely new to xsl, I suggest you invest some time reading at least the first three chapters of Tidwell's book:
https://www.google.com/search?tbm=bks&hl=en&q=xsl%2B%22The+Obligatory+Hello+World+Example%22+site%3Abooks.google.com

If you feel like skipping Chapter 1, I suggest you at least read the "XML Basics" section. The section titled "How a Stylesheet is Processed" in Chapter 2 is particularly illuminating. Chapter three covers node types and the "context node". These chapters should demystify these concepts and give you a good foundation into xsl.

Regards,
Hielo

i di d added
<?xml-stylesheet type="text/xsl" href="breakfast.xsl"?>

>> <?xml-stylesheet type="text/xsl" href="breakfast.xsl"?>
That was meant for you to do testing by opening the XML file directly through the browser. I don't know if Eclipse has built-in capabilities to do XSL transformation, but to the oracle link I referred you to earlier shows you how to do so in java.

please advise

Like I said, '<?xml-stylesheet type="text/xsl" href="breakfast.xsl"?>' was meant for you to test on the browser. Since you are not using the browser, get rid of it.
