Updating HelpNDoc script to locate library items in help topics - pascalscript

Question

I am trying to write a script to use with HelpNDoc.
I am part way there:
var
aList: THndLibraryItemsInfoArray;
nCnt: Integer;
begin
// Get all items in the library
aList := HndLibraryItems.GetItemList([]);
// Go through each of them
for nCnt := 0 to Length(aList) - 1 do
begin
// Is this a image (1)?
// Is this a image map (9) ?
if(HndLibraryItems.GetItemKind(aList[nCnt].id) = 1 or HndLibraryItems.GetItemKind(aList[nCnt].id) = 9) then
// What is the default alternate text?
var aDefaultAltText := HndLibraryItemsMeta.GetItemMetaStringValue(aList[nCnt].id, 'defaultalttext', '');
// Update the alternate text if required
if(aDefaultAltText = '') then
// Now what do we do? We need to find all instances of where this library item has been used.
// When we encounter one that has an alternate text description we update the meta.
// How?
end;
// What is the default padding?
var aDefaultPadding := HndLibraryItemsMeta.GetItemMetaIntValue(aList[nCnt].id, 'defaultpadding', 0);
// Update padding if required
if(aDefaultPadding = 0) then
HndLibraryItemsMeta.SetItemMetaIntValue(aList[nCnt].id, 'defaultpadding', 5);
end;
end;
end.
I can:
Iterate all library items
Isolate all image / image map items
Extract the default padding / alternate text values.
Update the default padding value to 5 if it is 0.
The issue is with the alternate text. If it does not have a default value then I want to do this:
Iterate all help topics
Iterate all library items used in each help topic
Find if the library item was used in that topic
If it was, it gets alternate text value.
If that value is not empty, apply it to the meta default value. Otherwise find the next instance.
If, by the end of iteration it did not find a alternate text value that was not empty it prints the library item name on screen.

Answer 1

It is not possible to do what I wanted via the API.
Response from HelpNDoc:
HelpNDoc's API doesn't include ways to iterate over topic content.
