Note:

The event fires before loading the requested file. After loading file and changing by keywords, the onPageModify event is fired.

Access to keywords is done by Vars property.

Example:

Event replaces the keyword XXtime by request current time (by VBScript function Now). If the word "_(XXtime)_" is contained in the document, then it will be replaced by the value of XXtime keyword (i.e. the current time) upon reading.

pMe.Vars("XXtime") = Now
