Answer 1

Use executeScript: (requires permission activeTab)

chrome.tabs.executeScript(null, {
    code: `document.all[0].innerText`,
    allFrames: false, // this is the default
    runAt: 'document_start', // default is document_idle. See https://stackoverflow.com/q/42509273 for more details.
}, function(results) {
    // results.length must be 1
    var result = results[0];
    process_result(result);
});

In case the code is complex, it's possible to define a function in the content script and call that function in the code (or use file).
