RE: [docbook-apps] Including plain text: CDATA

["Robert Shields" <rshields@star.net.uk>]

Hi,

You can do this:

<xsl:output cdata-section-elements="node"/>

where "node" is the name of the node you want to output as CDATA.

However, you shouldn't care whether it is output in CDATA sections or
not, as

<node>foo &amp; bar</node>

is the same as

<node><![CDATA[foo & bar]]></node>

as far as the processor is concerned.

Regards,

Rob Shields
