推荐答案

假定您已经将html源存储在名为htmlPage的String变量中.

Assuming you already have the html source stored in a String variable called htmlPage.

int iFrameIndex = htmlPage.indexOf("iframe");
int srcIndex = htmlPage.indexOf("src", iFrameIndex);
int httpIndex = htmlPage.indexOf("http", srcIndex);
int quotesIndex = htmlPage.indexOf("\"", httpIndex);
String srcUrl = htmlPage.substring(httpIndex, quotesIndex);
