Im having trouble deserializing with prefixes

#[derive(YaSerialize, YaDeserialize, Debug, Default, Clone, Eq, PartialEq)]
pub struct Header {}

#[derive(YaSerialize, YaDeserialize, Debug, Default, Clone, Eq, PartialEq)]
#[yaserde(
  rename = "Envelope",
  namespaces = {
    "soapenv" = "http://schemas.xmlsoap.org/soap/envelope/",
  },
  prefix = "soapenv"
)]
pub struct SoapEnvelope<BODY>
where
    BODY: YaSerialize + YaDeserialize + Default,
{
    #[yaserde(rename = "Header", prefix = "soapenv")]
    pub header: Option<Header>,
    #[yaserde(rename = "Body", prefix = "soapenv")]
    pub body: BODY,
}

#[derive(YaSerialize, YaDeserialize, Debug, Default, Clone, Eq, PartialEq)]
struct Body {
    #[yaserde(prefix = "urn")]
    text: String,
}

serializing the following:

let b = Body {
        text: "hello world".to_string(),
    };
let env = SoapEnvelope {
        body: b,
        ..Default::default()
    };

let s = yaserde::ser::to_string(&env).unwrap();

dbg!(s);

this yields:

"<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope" >
<soapenv:Body>
<urn:text>hello world</urn:text>
</soapenv:Body>
</soapenv:Envelope>

the text elements is serialized with the prefix

 let envelope = yaserde::de::from_str::<SoapEnvelope<Body>>(&s).unwrap();

this now errors with value: "text is a required field of Body"

when the prefix is removed from the text element it will serialize without a problem

"<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope" >
<soapenv:Body>
<text>hello world</text>
</soapenv:Body>
</soapenv:Envelope>

if this xml is deserialized with the urn prefix on the text element. the prefix is ignored and the xml is deserialized without error..
so it seems that the deserializer is ignoring the prefix.

Can you test with a valid struct ?
The urn is a prefix, but no namespace is declared.

#[derive(YaSerialize, YaDeserialize, Debug, Default, Clone, Eq, PartialEq)]
#[yaserde(
  namespaces = {
    "urn" = "http://example.com/",
  }
)]
struct Body {
    #[yaserde(prefix = "urn")]
    text: String,
}

Good day..
thx for the response..

im not sure what you mean by valid struct..
when i declare it with a namespace like above it does work
but body should not have a namespace.. as in the thing im serialize and deserialize does not have a namespace on the body. as a example what im trying to serialize and deserialize

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:something"  >
   <soapenv:Header/>
   <soapenv:Body>
      <urn:getProducts>
         <urn:manyfields>data in field</urn:manyfields>
      </urn:getProducts>
   </soapenv:Body>
</soapenv:Envelope>

as you can see there is no namespace one body, while the nested elements do have a prefix.

im am using 2 namespaces on the envelope like the following

#[derive(YaSerialize, YaDeserialize, Debug, Default, Clone, Eq, PartialEq)]
#[yaserde(
  rename = "Envelope",
  namespaces = {
    "soapenv" = "http://schemas.xmlsoap.org/soap/envelope/",
    "urn" = "urn:something"
  },
  prefix = "soapenv"
)]
pub struct SoapEnvelope<BODY>

The main issue is the miss of the declaration of "urn" = "urn:something"
Without that, no namespace prefix urn is declared, so it cannot be handled correctly.
