Getting element text from a source xml file with xslt

Question

I am brand new to XSL and am trying to get the information from a source file that is in this format:

<mailList>
    <subscriber familyname="Smith"
                givenname="Jon"
                email="[email protected]"/>
    <subscriber givenname="Luke"
                familyname="Sky"
                email="sov.com"/>

I have tried to use value-of but it just creates an empty element:

<xsl:template match="subscriber">
    <xsl:element name="entry">
      <xsl:element name="firstname">
        <xsl:value-of select="forename"></xsl:value-of>
      </xsl:element>

Any help would be greatly appreciated!

<xsl:template match="subscriber"> is fine for matching any of the subscriber input elements. Inside of that template you can select the data with e.g. xsl:value-of, but of course you have to select existing data, your attempt of select="forename" tries to select a child element of that name. Your subscriber elements don't have any child elements at all, there are only attributes, even those don't have that name forename.

To select an attribute you use e.g. select="@attribute-name", so for your sample e.g. select="@givenname".

As for creating result elements, while <xsl:element name="entry"> is possible, you can use literal result elements e.g.

  <entry>
    <firstname>
      <xsl:value-of select="@givenname"/>
    </firstname>
  </entry>
