I have the input.html belowI

**Input.html**
<https://jsfiddle.net/f86q7ubm/>

And I'm trying to match all elements within list `allList` with size=5, but when I run the following code, the matching has no values inside.

```
from bs4 import BeautifulSoup

fp = open("file.html", "rb")                 
soup = BeautifulSoup(fp,"html5lib")

allList = soup.find_all(True)

matching = [s for s in allList if 'size="5"' in s]  

```

What I'm doing wrong?
