im looking To scrape a specific element inside the raw HTML of a specific div using a Chrome extension,

const element = document.querySelectorAll('div.cardfront_content img.level');

const cardfrontContent = document.getElementsByClassName('cardfront_content')

// Loop through each div that has the cardfront content class
for(const content of cardfrontContent) {
    const levels = content.getElementsByClassName('level')
    
    // For each div, loop through each class name that has 'level'
    for(const level of levels) {
        // We have the level element here, and we can obtain the number from the class name by splitting level level to get the number
        console.log('value: ', level.className.split('level level')[1])
    }
}
