Command in Java for "all opened documents"

Question

I have a script that needs modification. Thank you all in the forum for helping me design this script from start btw!
Anyway, this is the script.
var myDoc = app.activeDocument;
app.findGrepPreferences = app.changeGrepPreferences = null;
// Change "Condition 1" to name of your condition
myConditionList = app.activeDocument.conditions.everyItem().getElements();
for (i=myConditionList.length-1; i>=0; i--)
    if (myConditionList[i].visible == false)
        myConditionList[i].visible = true;
        app.findGrepPreferences.appliedConditions = [myConditionList[i].name] ;
        app.findGrepPreferences.findWhat = ".+";
        myDoc.changeGrep();
        app.activeDocument.conditions.item(myConditionList[i].name).remove();
I'm looking for a variable that can apply for "all" opened documents rather than the active one only. I'm having difficulty finding the right command.
BTW, the script removes all hidden text and objects.

Programming has never been my strong side. Never understood it properly and probably never will =(. But thank you solving it. The code "JUMO_OVER" wrote, worked like charm. No need to execute the script 10x for 10 documents.
Pardon me for giving you guys more out headaches, I have two additional scripts that needs revision for the same purpose as above, i.e. able to exceute the scrip for all opened docs, saved or unsaved. I would really appreciated if you guys could help me convert them. I tried it do it on my own own, but I can't get it working... =(
Delete Empty Frames in active doc
var myStories = app.activeDocument.stories.everyItem().getElements();
for (i = myStories.length - 1; i >= 0; i--)
    var myTextFrames = myStories[i].textContainers;
    for (j = myTextFrames.length - 1; j >= 0; j--)
        if (myTextFrames[j].contents == "")
            myTextFrames[j].remove();
Delete Empty Pages in active doc
app.doScript("main()", ScriptLanguage.JAVASCRIPT, undefined, UndoModes.ENTIRE_SCRIPT,"Remove  Blank Pages");
function main () {
    if (app.documents.length === 0) {
        alert ("Please open a document.");
        return;
    app.scriptPreferences.enableRedraw = false;
    removeBlankPages (app.Documents);
    app.scriptPreferences.enableRedraw = true;
    function removeBlankPages (doc) {
        var pages = doc.pages.everyItem().getElements().slice(0);
        var i = pages.length;
        while (i-- >1) { // a bit quicker here
            !pages[i].allPageItems.length && pages[i].remove ();
        !pages[i].allPageItems.length && pages[i] != doc.pages[-1] && pages[i].remove ()
BTW, I didn't write them. So they may look quirky in your eyes.
