== Usage ==
For example, the article [[:en:Ophir, Alaska]] contains this text:

 <nowiki>{{otherusesof|Ophir}}
 '''Ophir''' is an unincorporated area located
 at {{coor dms|63|08|41|N|156|31|10|W|}}</nowiki>

Copy the source code below and save as extraktor.pl, then apply to the uncompressed XML dump like this:

 perl extraktor.pl <enwiki-20060816-pages-articles.xml >enwiki.parameters

For the page above, this script should produce the following output:

 Otherusesof|Ophir, Alaska|1|1|Ophir
 Coor dms|Ophir, Alaska|2|1|63
 Coor dms|Ophir, Alaska|2|2|08
 Coor dms|Ophir, Alaska|2|3|41
 Coor dms|Ophir, Alaska|2|4|N
 Coor dms|Ophir, Alaska|2|5|156
 Coor dms|Ophir, Alaska|2|6|31
 Coor dms|Ophir, Alaska|2|7|10
 Coor dms|Ophir, Alaska|2|8|W
 Coor dms|Ophir, Alaska|2|9|

In this simple case, there are only position parameters without names, and no advanced syntax. The output is line-oriented with the vertical bar (|) as field separator. Each line has three or five fields.

#The first field is the name of the called template.
#The second field is the name of the page from where the template was called.
#The third field is a sequence number of this call within the page.
#The fourth field is the name (where applicable) or positional number of a parameter in this call.
#The fifth field is the value of this parameter in this call.

For template calls without parameters, e.g. <nowiki>{{stub}}</nowiki>, fields 4 and 5 are left out.
