How to apply a filter in XML to import the records using PHP?

Question

I have an XML with several records to make an import with PHP. The importing part is ok, but I wanted to make a filter before importing, for example, import only the record that has ID 444, how can I do this?

I thought to download the xml edit and save as a new XML, would that?

XML example:

<Imoveis>
 <Imovel>
  <Id>123</Id>
 </Imovel>
 <Imovel>
  <Id>444</Id>
 </Imovel>
</Imoveis>

I’m using the $xml = new SimpleXMLElement($return) to download xml, where $return is the XML value returned from an API.
