What is the best way to retrieve text with xpath from an angular-based webpage?

Previously, google voice had a method to extract SMS codes using a "div" element. Recently, they made the switch to an ARIA-based framework with AngularJS. How can I now retrieve the string containing all my SMS codes from the webpage?

Below is the command I have been utilizing along with the target XPath:

var search2 = document.evaluate('//*[@id="messaging-view"]/div/md-content/div/gv-conversation-list/md-virtual-repeat-container/div/div[2]/div[1]/div/gv-text-conversation-item/gv-conversation-item/div/div[2]/ng-transclude/gv-conversation-item-detail/gv-annotation/text()',
  document, null, XPathResult.ANY_TYPE, null);

This is the result that appears in my Chrome Developer console

Answer №1

For more information on XPath in JavaScript, refer to the Mozilla documentation. What you receive back is known as a node iterator, which is a common return type for an XPath query when specifying ANY_TYPE. To adjust your code to function properly, consider the following:

// Storing your query in a variable for better visibility
var query = '//*[@id="messaging-view"]/div/md-content/div/gv-conversation-list/md-virtual-repeat-container/div/div[2]/div[1]/div/gv-text-conversation-item/gv-conversation-item/div/div[2]/ng-transclude/gv-conversation-item-detail/gv-annotation/text()';
var search2 = document.evaluate(query, document, null, XPathResult.ANY_TYPE, null);

var thisNode = iterator.iterateNext();

while (thisNode) {
    console.log(thisNode.textContent); // most likely a text node
    thisNode = iterator.iterateNext();
}

Alternatively, you can simplify by specifying the result type as STRING_TYPE.

// Storing your query in a variable for better visibility
var query = '//*[@id="messaging-view"]/div/md-content/div/gv-conversation-list/md-virtual-repeat-container/div/div[2]/div[1]/div/gv-text-conversation-item/gv-conversation-item/div/div[2]/ng-transclude/gv-conversation-item-detail/gv-annotation/text()';
var search2 = document.evaluate(query, document, null, XPathResult.STRING_TYPE, null);

console.log(search2.stringValue);
