Alternative option to getTraversalObj() in version 4.2.4

[miguel-padilla92]

Hello there

I'm trying to update a library called s3rver and they have a function to return the xml root tag

const traversal = xmlParser.getTraversalObj(xml.toString()); 
const [[root]] = Object.values(traversal.child);  
return root && root.tagname;

but since getTraversalObj is no longer in version 4.2.4 what would be the alternative way of doing it

this is an example of how it looked before trying to update the fast-xml-parser version

xml:  
<WebsiteConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <IndexDocument>
        <Suffix>index.html</Suffix>
    </IndexDocument>
    <ErrorDocument>
        <Key>error.html</Key>
    </ErrorDocument>
</WebsiteConfiguration>
traversal:  
{
  tagname: '!xml',
  parent: undefined,
  child: { WebsiteConfiguration: [ [Object] ] },
  attrsMap: {},
  val: undefined,
  addChild: [Function (anonymous)]
}
root:  
{
  tagname: 'WebsiteConfiguration',
  parent: {
    tagname: '!xml',
    parent: undefined,
    child: { WebsiteConfiguration: [Array] },
    attrsMap: {},
    val: undefined,
    addChild: [Function (anonymous)]
  },
  child: { IndexDocument: [ [Object] ], ErrorDocument: [ [Object] ] },
  attrsMap: undefined,
  val: '',
  addChild: [Function (anonymous)]
}
config:  
S3WebsiteConfiguration {
  type: 'website',
  rawConfig: {
    WebsiteConfiguration: {
      '@_xmlns': 'http://s3.amazonaws.com/doc/2006-03-01/',
      IndexDocument: [Object],
      ErrorDocument: [Object]
    }
  },
  indexDocumentSuffix: 'index.html',
  errorDocumentKey: 'error.html'
}

Thanks in advance
