Similar to my earlier problems with finding a textFrame on a page based on its geometricBounds or by part of its name, I now am running into the problem of finding textFrames if they are inside groups. If I use an array of all textFrames, such as:
var textFramesArray = document.textFrames.everyItem().getElements();
it will not find any textFrames that are inside of a group. How can I figure out how to reference a textFrame if it's inside a group? Even if the group has to be un-grouped, that's fine, but I cannot even figure out how to find groups on the page!
Groups on a page are page.groups ... but you don't need this anyway. Fabian's answer is good, but it doesn't take groups-in-groups into account -- nor clipping masks, nor text frames inside tables and footnotes (etc.).
Here is an alternative approach: allPageItems is pretty much guaranteed to return all page items, of all kinds and persuasion, inside groups or other frames or whatnot. You can inspect, then process, each of them in turn, or build an array of text frames to work with at leisure:
allframes = app.activeDocument.allPageItems;
textframes = [];
for (i=0; i<allframes.length; i++)
{
if (allframes[i] instanceof TextFrame)
textframes.push(allframes[i]);
}
alert (textframes.length);
