• For working this preset required version of A-Parser is not lower than 1.1.336.
• In this preset for example used a parser SE::Google.
• Besides statistics outputs the standard result, it can be changed as usual.
• To the general format of the result is added the template, which counts the desired statistics:
  
  
• Domains are extracted in template by a regular expression (it is necessary to calculate the count of links for each domain).
• In the Prepend text variables are declared:
  
  
• In the Append text statistics are outputs:
  
  

That is written in the Prepend and Append texts, output at the beginning and end of the file (which is equivalent to the beginning and end of parsing). Thanks to common space variables, it is possible to organize a one-time output of statistics or other data with support Template Toolkit templates.

An example of output statistics:
