How to get contents string from itemByRange?

Dear all,

Here is what I am trying to achieve:

I selected a word and want to get the contents of the 1^st word in the string (the name of a person).

In fact, the selected text is the source* of a hyperlink and my goal is to get the person’s name it points to.

*selection[0] is the same as hyperlink.source.sourceText

Since I can’t get the paragraph or line where the selected word is (or simply don't know how to do this), I am trying to get it from the story: starting from the 1^st character of the selected word and moving backwards character by character comparing its contents. When it hits “\r”, I know that’s the beginning of the line. This way I can get the part of the line I am interested in with itemByRange() method which returns “Array of Character”.

Main();
function Main() {
    var doc = app.activeDocument;
    var sel = app.selection[0];
    GetName(sel);
}
function GetName(txt) {
    var lastCharacter = txt.characters[0];
    var character = txt.characters[0];
    var story = txt.parentStory;
    var index = lastCharacter.index;
    while (character.contents != "\r") {
        character = story.characters[index];
        index--;
    }
    // Array of Character itemByRange (from: varies, to: varies)
    // Returns the Characters within the specified range. 
    var arr = story.characters.itemByRange(character, lastCharacter);
    var str1 = arr.contents[0];
    var str2 = str1.match(/^\S+/);
    return str2;
}

My problem is that I can’t get the contents -- str1 -- by script. However, I can see in Data Browser that it’s there. If I click str1, it shows up:

If I type str1 in Console, I get it too:

I also tried to use:

arr.getElements()

arr.getElements()[0]

arr.getElements()[0].contents

…

etc.

but it didn’t work either.

I must be missing something very obvious, but I am stuck. Can anybody help me, please?

Regards,

Kasyan
