XSL placeholders
The following syntax is used within an XSL transformation in a data island.
HeaderOverride
By embedding this content and putting XSL field elements within the tags the standard tags within the HTML <HEAD> are over written. This allows the developer to create a database driven page with differing title and header attributes depending on the content of the page.
In 10.5 support for a generic header override syntax was added to the CMS which can be embedded anywhere to add extra head tags that the CMS does not automatically provide.
Syntax: (10.2 canonical added)
<headoverride>
<title></title>
<keywords></keywords>
<description></description>
<canonical></canonical>
</headoverride>
Example:
The example embeds content from the XSL. It can be placed anywhere in the body of the XSL though it's usually easier to use it at the top
<headoverride>
<title><xsl:value-of select="BusinessName"/>, <xsl:value-of select="town" /> | Hostel <xsl:value-of select="region" />
Scotland | <xsl:value-of select="town" /> Hostel Accommodation</title>
<description>A warm welcome awaits you at <xsl:value-of select="BusinessName" /> in <xsl:value-of select="town" />,
<xsl:value-of select="region" />, a quality assured, independent hostel offering excellent budget accommodation.</description>
<keywords><xsl:value-of select="BusinessName"/>, Independent Hostel <xsl:value-of select="town" />,
<xsl:value-of select="town" /> Hostel Accommodation, <xsl:value-of select="town" /> Youth Hostel</keywords>
<canonical>http://:::domain:::<xsl:value-of select="RESTURL"/></canonical>
</headoverride>
