FrameLocator frameLocator = page.frameLocator("#javaTutorial");
System.out.println("title : " + frameLocator.locator("title").textContent());

<!DOCTYPE html>
<html>

<head>
	<title>iframe demo</title>
</head>

<body>

	<h1>iframe demo</h1>

	<iframe src="https://self-learning-java-tutorial.blogspot.com/2018/08/spring-framework.html"
		id="springFrameworkTutorial" width="800" height="500"></iframe>

FileUtil.java

package com.sample.app.util;

import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

public class FileUtil {

	public static String resourceAsString(String resourceName) throws IOException {
		ClassLoader classLoader = FileUtil.class.getClassLoader();
		URL url = classLoader.getResource(resourceName);
		if (url == null) {
			return null;
		}

		URLConnection urlConnection = url.openConnection();

		urlConnection.setUseCaches(false);

		try (InputStreamReader inputStreamReader = new InputStreamReader(urlConnection.getInputStream())) {
			char[] buffer = new char[1048];
			StringBuilder builder = new StringBuilder();

			int count = -1;
			while ((count = inputStreamReader.read(buffer, 0, buffer.length)) != -1) {
				builder.append(buffer, 0, count);
			}

			return builder.toString();
		}

	}
}

 

IFrameDemo.java

package com.sample.app.locators;

import java.io.File;
import java.io.IOException;

import com.microsoft.playwright.Browser;
import com.microsoft.playwright.BrowserType;
import com.microsoft.playwright.FrameLocator;
import com.microsoft.playwright.Page;
import com.microsoft.playwright.Playwright;
import com.sample.app.util.FileUtil;

public class IFrameDemo {
	public static void main(String[] args) throws IOException {
		try (Playwright playwright = Playwright.create()) {

			Browser browser = playwright.chromium()
					.launch(new BrowserType.LaunchOptions().setHeadless(false).setSlowMo(100));

			final String content = FileUtil.resourceAsString("locators" + File.separator + "iframe.html");

			Page page = browser.newPage();
			page.setContent(content);

			FrameLocator frameLocator = page.frameLocator("#javaTutorial");
			System.out.println("title : " + frameLocator.locator("title").textContent());

			frameLocator = page.frameLocator("#springFrameworkTutorial");
			System.out.println("title : " + frameLocator.locator("title").textContent());

		}
