I am looking for a php programmer who can create a small script

I am looking for a php programmer who can create a small script that does the following:
The following address is an xml file and has product images:
https://www.grupocva.com/catalogo_clientes_xml/imagenes_alta.xml?cliente=48346&clave=SAM-319

in the following format:

<product>
<image>http://www.grupocva.com/detalle_articulo/img_large.php?id=240139</image>
<image>http://www.grupocva.com/detalle_articulo/img_large.php?id=240140</image>
<image>http://www.grupocva.com/detalle_articulo/img_large.php?id=240141</image>
</product>

I need a program that searches the xml file for the images and downloads the first image with the name of the key in this example is SAM-319 and the name of the image would be SAM-319.jpg

what changes in this program are the keys, the ideal thing would be to be able to do it en masse, since there are more than 5000 keys.

I have a hosting, in which you can give access to do the script.
