Talk:Test includematch

Includematch searches all fields instead of just one (bug?)

I tested the following example and noticed strange includematch behaviour.

<dpl>
category=African Country
includepage={African Country}:languages,{African Country}:government_type,{African Country}:area,{African Country}:population,{African Country}:gdp,{African Country}:independence_day
mode=userformat
listseparators=¶{|class=sortable ¶!No ¶! Name ¶! Languages ¶! Government ¶! Area ¶! Population ¶! GDP ¶! Independence Day , ¶|-¶|%NR%¶|[[%PAGE%]] , ,¶|}
secseparators=¶|
resultsheader=Number of data = %PAGES%
includematch=/languages\s*=\s*.*English.*/s
</dpl>

Try for example replacing

includematch=/languages\s*=\s*.*English.*/s

with

includematch=/languages\s*=\s*.*1961.*/s

and you still got a result because the "Independance day" column is searched. Shouldn't only the "Languages" column being searched? --Mark P. 23:25, 22 November 2007 (CET)

Explanation

No, this is not a bug. As explained titlematch applies the regep to the whole string used for the temlate´s invocation. It is your responsibility to define the pattern in a a way that in will only match the contents youz are seeking for.

In the above example the ".*" before English or before 1961 causes the surprising behaviour. ".*" means anything, even a pipe separator. So the pattern simply looks if SOMEHWERE in the complete invocatrion string it can find the literal languages and SOMEWHERE afer that place 1961 can be found.

Replace '.*' by '[^|]*' and it will do what you expect because now the regexp looks for languages and then it skips all non-fitting characters EXCEPT the pipe symbol.

Note: If you use the #dpl parser function notation you must use an octal notation for the pipe or escape it vi a media wiki template which produces a pipe.

Example:

looking for 'English' Number of data = 2

No	Name	Languages	Government	Area	Population	GDP	Independence Day
1	Republic of Cameroon	French,English		183,568 sq mi	17,795,000	$43.196 billion	01/10/1961
2	United Republic of Tanzania	Swahili, English		364,898 sq mi	37,849,133	$27.12 billion	26/04/1964

looking for '1961'

Extension:DynamicPageList (DPL), version 3.2.1: Warning: No results.

No	Name	Languages	Government	Area	Population	GDP	Independence Day

with parser function syntax looking for 'English' Number of data = 3

Name	Languages	Government	Area	Population	GDP	Independence Day
