Script that can be run from Inspector Console; Flattens Axure Wireframe site into a text file with hyperlinks to pages (can be side-loaded into other tooling if required).

Axure-Flatten.js

// Get Sitemap
var axureNodes = $axure.document.sitemap.rootNodes;

// Parse sitemap for URLs
var key = 'url';
var normalisedAxureNodes = function getValues(obj, key) {
    var objects = [];
    for (var i in obj) {
        if (!obj.hasOwnProperty(i)) continue;
        if (typeof obj[i] == 'object') {
            objects = objects.concat(getValues(obj[i], key));
        } else if (i == key) {
            objects.push(obj[i]);
        }
    }
    return objects;
}(axureNodes, key);

// Prepare file contents
var myfilecontents = function buildTextFile(my_values){
    var textfilecontents = '';
        for (var i in my_values) {
        if(my_values[i] != '')
            textfilecontents += 'http://' + window.location.hostname + '/' + my_values[i] + '\n';
    }
    return textfilecontents;
}(normalisedAxureNodes);

// Open file in browser
var url = 'data:text;charset=utf8,' + encodeURIComponent(myfilecontents);
window.open(url, '_blank');
window.focus();
