tal:omit-tag
syntax:
argument ::= [ expression ]
The tal:omit-tag
statement leaves the contents of a tag in place
while omitting the surrounding start and end tag.
If its expression evaluates to a false value, then normal processing of the element continues and the tag is not omitted. If the expression evaluates to a true value, or there is no expression, the statement tag is replaced with its contents.
Zope treats empty strings, empty sequences, zero, None, nothing, and default at false. All other values are considered true.
Unconditionally omitting a tag:
<div tal:omit-tag="" comment="This tag will be removed"> <i>...but this text will remain.</i> </div>
Conditionally omitting a tag:
<b tal:omit-tag="not:bold">I may be bold.</b>
The above example will omit the b
tag if the variable bold
is
false.
Creating ten paragraph tags, with no enclosing tag:
<span tal:repeat="n python:range(10)" tal:omit-tag=""> <p tal:content="n">1</p> </span>
