Codecept可以看到RSS feed（XML）中的元素吗？

Question

I have an RSS feed which should have only 1 'item' in it. I know that I can do I.see() to check that any number exists; but is it possible to check if exactly 1 exists?

I know for elements (in html) I have much more flexibility than simply I.see(). Is it possible to see xml as elements?

Answer 1

const DOMParser = require('xmldom').DOMParser;
let parser = new DOMParser();
let elementTagName = "rss"; // set tag of your element here
let xmlXpath = "//body/pre";

I.waitForElement(xmlXpath);
let innerText = await I.grabTextFrom(xmlXpath);
let documentCustom = parser.parseFromString(innerText, "text/xml");
let documentCustomGetElement = documentCustom.getElementsByTagName(elementTagName)[0].childNodes; // your element here

You can try it for this rss-feed .
