Filter by RegEx

Description

Selects objects by the value of a string property, using regular expression replacement.

Input

SOURCE [OBJ]: the list of objects to filter

Output

TRUE [OBJ]: the objects for which the selection applies
FALSE [OBJ]: the objects for which the selection does not apply

Parameters

Property: the string property to check. Use * to consider all properties.
Use sub-properties: when set to true, the values of all sub-properties are also included. Sub-properties can be defined in the data with the rdfs:subPropertyOf relation.
Pattern RegEx: the regular expression to use for the match.
Language: when a language is selected, only the strings in this language are extracted. This uses the language tags that are defined in the data.
Case-sensitive: if set to false, upper/lower case is ignored

Output scores can be aggregated and/or normalized.

Regular Expressions

Regular expressions are internally evaluated by a PCRE engine. For a syntax reference, see this page. For a 1-page syntax reference, see this cheat-sheet.

Some of the Most Common Questions and Mistakes

Regular expressions are different from glob patterns using wildcards. In particular, * does NOT mean "anything", .* does.
All special characters (. * + ? | \ ( ) [ ] ^ $) must be escaped (prefixed with \) when they are meant literally, in the Pattern RegEx.
^ indicates the beginning of an input text, or negation when used inside a multiple choice (e.g., [^\d-_]). $ indicates the end of an input text.
\b indicates a word-boundary (spaces, punctuation, etc.).

Examples

Find names in the form of Smith, John:
- Pattern RegEx: \b[^,]+\s*,\s*\b\w+\b
Find any day of the week (with Case-sensitive = false):
- Pattern RegEx: \b(mon|tue|wednes|thurs|fri|sat|sun)day\b
