Try using document.querySelectorAll() with selector "meta[expr\\:content]" , for loop , .getAttribute() 

var metas = document.querySelectorAll("meta[expr\\:content]");

for (i = 0; i < metas.length; i++) {
  console.log(metas[i].getAttribute("expr:content"))
}
<meta expr:content='data:blog.blogId' itemprop='blogId' />
<meta expr:content='data:post.id' itemprop='postId' />
