[记]在rust中使用xml，xml的序列化与反序列化

序

在rust中有好几个xml库，但我个人比较推荐的是quick_xml库，这个库的序列化和反序列化使用体验比较好。

启用quick_xml的feature

quick-xml = { version = "0.31.0",features=["serde","serialize"] }
serde = {version="1.0",features=["derive"]}

qucik_mxl的宏体验

依靠强大的宏，quick_xml使用结构体和枚举即可实现xml结构的一一对应。

pub struct CalibrationData{
    #[serde(rename = "@xmlns:xsi")]
    xmlns:String,
    CalConfig:Vec<CalConfig>,
}

<CalibrationData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
...
</CalibrationData>

#[derive(Deserialize)]
struct AnyName {
  #[serde(rename = "@one")]
  one: T,

  #[serde(rename = "@two")]
  two: U,
}

<any-tag one="..." two="..."/>

#[derive(Deserialize)]
struct AnyName {
  one: T,
  two: U,
}

<any-tag>
  <one>...</one>
  <two>...</two>
</any-tag>

#[derive(Deserialize)]
struct AnyName {
  #[serde(rename = "@field")]
  attribute: T,
  field: U,
}

<any-tag field="...">
  <field>...</field>
</any-tag>

#[derive(Deserialize)]
struct AnyName {
  #[serde(rename = "@optional")]
  optional: Option<T>,
}

<any-tag optional="..."/><!-- Some("...") -->
<any-tag optional=""/>   <!-- Some("") -->
<any-tag/>               <!-- None -->

#[derive(Deserialize)]
struct AnyName {
  #[serde(default)]
  item: Vec<Item>,
}

<any-tag>
  <item/>
  <item/>
  <item/>
</any-tag>

    use serde::Serialize;
    use quick_xml::writer::Writer;
    use quick_xml::se::Serializer;
    use quick_xml::de::from_str;
    use quick_xml::reader::Reader;

        if let Ok(sd) = quick_xml::se::to_string(&sedd){
            println!("sd{}",sd);
        }

let okxml =std::fs::read_to_string("CalDB_NET.xml")?;
let sedd = from_str::<CalibrationData>(&okxml).unwrap();
