Reading file XML with XPath query

Good morning I need to extrapolate a series of values through XPath queries from XML files that I report at end of the page.

I'm able to obtain the values of my interest until the FileGroup level of the schema, for example with a query like //FileGroup/File/Path

However, I cannot read the data contained in the EmbeddedMetadata node

I have tried in various ways such as for example // FileGroup / File / MoreInfo / EmbeddedMetadata / SubjectDestinatario / Denominazione and others but I don't get the correct query In particular it would be useful for me to read the values contained for example in Tag such as:

<FileNameOriginale> IT09533610011_173.xml </FileNameOriginale>

<SubjectDestinatario role = "Addressee" type = "organization">
   <Denomination> REWIND Srl </Denomination>

<MetadataAggiuntivi name = "NumeroDocumento"
   value = "2020047"

Precisely in this case i would like read: IT09533610011_173.xml REWIND Srl 2020047

Thank you very much in advance who will be kind enough to help me

Solution

If it is XPath 1 then either learn how bind a prefix (e.g. idv) to the namespace http://archismall.com/IDV_EmbeddedMetadata_XSD.xsd in your environment and then use it as in e.g. //idv:MoreInfo/idv:EmbeddedMetadata/idv:FileNameOriginale to select elements in that namespace or go for the local name e.g. //*[local-name() = 'MoreInfo']/*[local-name() = 'EmbeddedMetadata']/*[local-name() = 'FileNameOriginale'].

With XPath 2 or 3 can always use namespace wildcards e.g. //*:MoreInfo/*:EmbeddedMetadata/*:FileNameOriginale for those elements that are in a namespace. In XPath 3 you can even include the namespace URI in each step of a path e.g. Q{http://archismall.com/IDV_EmbeddedMetadata_XSD.xsd}EmbeddedMetadata.
