TagCheck HTML and XML tag validator with editing

A freeware program for 32-bit Windows

TagCheck tests your HTML or XML code to ensure that all the tags are properly nested and closed. It does not validate anything else. It adds a context menu item to HTML and XML files, but does not change any file associations. If you select the "Check with TagCheck" context menu item when TagCheck is already running the file is checked by the existing instance.

If you check one file at a time, the text is displayed in the main window with the errors marked in red. You can use TagCheck to correct the errors, save it and check it again. Alternatively, you can check a batch of files. In that case a list of the files is shown, annotated with the number of errors found in each.

You can modify the lists of tags for which a closing tag is forbidden (such as META and BR) and those for which a closing tag is optional (such as P and LI). All other tags must be closed. Editing the lists allows you to check tags which you habitually close even though it's not required.

XML parsing is activated either by an XML file extension or finding a <?xml......> tag. An indicator on the status bar shows which mode is in force. There are two differences between HTML mode and XML mode.

  • In XML mode all tags must be closed except those for which it is forbidden.
  • Sections between square brackets [...] are parsed as a separate unit. Within the brackets all tags must be correct. The text outside the brackets is treated as if the bracketed section had been removed.
