::hwat::xml::private::XMLStart str_elemName str_attrList

Arguments

str_elemName: The name of the element to handle.
str_attrList: The interlaced attribute list.

Returns

N/A

Example

::hwat::xml::private::XMLStart $str_myElement [list var1 1 var2 2 var3 3]

Comments

This is an internal, private function for the XML parser. This function should not be called directly. The user should make use of the ::hwat::xml::RegisterCallback function to register his/her own element event callback.
