Question

I have an XQuery return statement like:

return
 <li>
 <h3>{ string($TELECAST/title/maintitle) }</h3>
 <h4>{ string($TELECAST/title/subtitle) }</h4>
 <h5>{ string($TELECAST/title/description) }</h5>
 </li>

Sometimes, there is no subtitle or description, still the HTML tags will be output. How can I easily check for empty strings and omit the unnecessary tags?

Answer 1

For example, like this:

return
 <li> {
 for $i in $TELECAST/title/maintitle return <h3>{ string($i) }</h3>,
 for $i in $TELECAST/title/subtitle return <h4>{ string($i) }</h4>,
 for $i in $TELECAST/title/description return <h5>{ string($i) }</h5>
 } </li>
