What I'm trying to get is an array that contains all the description value like this :

var myArray = ['First Description', 'Second Description', 'Third Description']

So, I'm doing a request to an API and I read my value like this :

const xmlDoc = new DOMParser().parseFromString(xmlStr, "application/xml");
let firstDescription = xmlDoc.evaluate('Response/QueryListResponse/DomainEntity/Property[1]/value/text()') 
console.log(firstDescription.stringValue) -- Display : First Description

But the problem with this solution is that I have only one description. So I tried to get a dom element and to navigate into it

So with this code :

x = xmlDoc.getElementsByTagName("QueryListResponse")[0];

I got a DOM element with all the values like this :

<QuerySelector>
    <MetaData></MetaData>
    <DomainEntity>
        <Property path="description">
            <Value>First Description</Value>
        </Property>
    </DomainEntity>
    <DomainEntity>
        <Property path="description">
            <Value>Second Description</Value>
        </Property>
    </DomainEntity>
    <DomainEntity>
        <Property path="description">
            <Value>Third Description</Value>
        </Property>
    </DomainEntity>
</QuerySelector>

So to get all my description I had two idea ...

The first one is to use the first solution and to use a for like this :

for (i; i <= nbOfValues; i++) {
    let v = xmlDoc.evaluate('Response/QueryListResponse/DomainEntity/Property['+i+']/value/text()') 
    myArray += v.stringValue
}

But I don't know how to find the nbOfValues .

So I think the solution of the DOM element is easier.

I think I have to do something like document.getElementByPath('description)' but it didn't work.

Any idea?
