For example i have the following XML file:
In each phrase, I always have 2 `<en>` tags and `x` attribute is either PERS, LOC or ORG.  

What I want to do is get all `<en>` pairs in which they are ORG & PERS only

XML Sample:

```
<PHRASE>
<N y='0'> back</N>
<en x='PERS'>John</en>
<PREP>to</PREP>
<en x='LOC'>New York</en>
</PHRASE>

```

I am using element tree, I tried that, but it retrieves any PERS or ORG no matter what is the second "en" tag. And I only want PERS and ORG pairs (i.e.: when they appear in the same phrase)

```
for en in root.findall('./PHRASE/en'):
    NE = en.get('x')
    if(NE) == "ORG":
     print("ORG is: ",en.text)
    NE2=en.get('x')
    if(NE2) == "PERS":
        print("PER is:", en.text)

```
