ns_tagelementset - Set the value of the value attribute in an HTML element
This command takes a variable name to upvar, tagvar. The variable should exist in the calling environment and should contain an HTML element that has had its closing ">" removed. The string is searched for the attribute attribute, which will be removed if found. A value attribute will be added to the end of the string with value value, which will be surrounded with double quotes. This procedure does not close the tag with a ">".
% set tag {<input type="hidden" name="myfield" value="100"}
<input type="hidden" name="myfield" value="100"
% ns_tagelementset tag value 250 <input type="hidden" name="myfield" value="250"
NOTES I believe using "value" as the attribute name in the output instead of the passed in attribute may be a bug.
