Tag Identifier


Service «Tag Identifier» is designed to obtain supporting information about the tags in the text. At the entrance of the service, you can submit arbitrary text or a sequence of characters with tags. At the output, the user receives the following supporting information about the tags in the text:

  • a list of tags (single or only opening) according to the order in which they occur in the text;
  • frequency of use of each tag (in brackets next to the tag name);
  • the part of the code that contains the listed tag, and in it:
    • context of use (black);
    • tag content from opening to closing (red).

 

Practical value

The service helps to navigate large texts of html markup: check for the presence of a specific tag, the closeness of the tag, its content and context of use, and thus detect errors in the markup.
