The regular expression `[0-9]{2}` matches two consecutive digits. Because it contains square brackets, the way to use it with the <<.op regexp>> operator is via a [[variable|Variables]], as follows:
|
|
|
|
<$macrocall
|
|
$name="wikitext-example-without-html"
|
|
src="""<$set name="digit-pattern" value="[0-9]{2}">
|
|
<<list-links "[regexp:title<digit-pattern>]" field:"title">>
|
|
</$set>"""/>
