XSLT not displaying

Question

I am new to XML - XSLT transformation. I have the following XML file and the corresponding XSLT file but for some reason, it does not display anything pass the h2, which is an HTML. Any help will be great!

I have checked the namespace to make sure it matches the XML document, and I also tried running code on the W3 site as well.

Both files are below:

XSLT

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
    <xsl:template match="/">
        <html>
            <body>
                <h2>Alphaba Resume - Long version</h2>
                <xsl:for-each select="alphabafictional_resume/objective">
                    <h2><xsl:value-of select="objective"/></h2>
                </xsl:for-each>
            </body>
        </html>
    </xsl:template>
</xsl:stylesheet>

Answer 1

You mention that you have "checked the namespace to make sure it matches the XML document", but there is no reference at all to the namespace "https://swe.umbc.edu/~asacko1/xs" in your XSLT.

In your XML, "https://swe.umbc.edu/~asacko1/xs" is the default namespace. In XSLT 1.0, the way to handle these is to declare it with a namespace prefix, and use that prefix throughout the XSLT.

Try this XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:swe="https://swe.umbc.edu/~asacko1/xs">
<xsl:output method="html"/>
    <xsl:template match="/">
        <html>
            <body>
                <h2>Alphaba Resume - Long version</h2>
                <xsl:for-each select="swe:alphabafictional_resume/swe:objective">
                    <h2><xsl:value-of select="swe:obj_body"/></h2>
                </xsl:for-each>
            </body>
        </html>
    </xsl:template>
</xsl:stylesheet>

Note that the choice of prefix here (swe) is arbitrary. It could be anything, just as long as the namespace URI matches.

If you could use XSLT, things are slightly simpler when it comes to default namespaces, as you could use xpath-default-namespace instead, and not have to worry about adding a prefix:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xpath-default-namespace="https://swe.umbc.edu/~asacko1/xs">
<xsl:output method="html"/>
    <xsl:template match="/">
        <html>
            <body>
                <h2>Alphaba Resume - Long version</h2>
                <xsl:for-each select="alphabafictional_resume/objective">
                    <h2><xsl:value-of select="obj_body"/></h2>
                </xsl:for-each>
            </body>
        </html>
    </xsl:template>
</xsl:stylesheet>

Answer 2

My XSL will take care of converting the output into text for the <h2> tags. The XSL is more flexible in case someone embeds an objective somewhere in the resume that you didn't expect.

  <xsl:for-each select="//*[name()='obj_body']">
      <h2><xsl:value-of select="."/></h2>
  </xsl:for-each>

I use name() because the namespace isn't well defined so obj_body needs to be evaluated as a string.

Answer 3

You're iterating through objective elements, and trying to output the value of another objective element within each, but there aren't any. Should you be doing

<xsl:value-of select="obj_body"/>

instead?
