将XML转换为Kotlin数据类

问题描述

对于Kotlin和翻新我还是很陌生。我正在使用arXiv API开发一个Android应用。它们以 Atom XML 格式提供查询结果。因此，我打算将 SimpleXML 转换器与 Retrofit 一起使用。现在，我遇到了从Atom XML响应生成Kotlin数据类的问题。

例如，向URL http://export.arxiv.org/api/query?search_query=all:electron&start=0&max_results=2发送 GET 请求后，我得到以下响应

    <?xml version="1.0" encoding="UTF-8"?>

    <title>Impact of Electron-Electron Cusp on Configuration Interaction Energies</title>
    <summary>  The effect of the electron-electron cusp on the convergence of configuration
interaction (CI) wave functions is examined. By analogy with the
pseudopotential approach for electron-ion interactions,an effective
electron-electron interaction is developed which closely reproduces the
scattering of the Coulomb interaction but is smooth and finite at zero
electron-electron separation. The exact many-electron wave function for this
smooth effective interaction has no cusp at zero electron-electron separation.
We perform CI and quantum Monte Carlo calculations for He and Be atoms,both
with the Coulomb electron-electron interaction and with the smooth effective
electron-electron interaction. We find that convergence of the CI expansion of
the wave function for the smooth electron-electron interaction is not
significantly improved compared with that for the divergent Coulomb interaction
for energy differences on the order of 1 mHartree. This shows that,contrary to
popular belief,description of the electron-electron cusp is not a limiting
factor,to within chemical accuracy,for CI calculations.

    <title>Electron thermal conductivity owing to collisions between degenerate
  electrons</title>
    <summary>  We calculate the thermal conductivity of electrons produced by
electron-electron Coulomb scattering in a strongly degenerate electron gas
taking into account the Landau damping of transverse plasmons. The Landau
damping strongly reduces this conductivity in the domain of ultrarelativistic
electrons at temperatures below the electron plasma temperature. In the inner
crust of a neutron star at temperatures T &lt; 1e7 K this thermal conductivity
completely dominates over the electron conductivity due to electron-ion
(electron-phonon) scattering and becomes competitive with the the electron
conductivity due to scattering of electrons by impurity ions.

从响应中，如果我们查看一个 Author 标记，我们将得到如下所示的内容（为了方便阅读，我添加了行号）

1. <author>
2.     <name>David Prendergast</name>
3.     <arxiv:affiliation xmlns:arxiv="http://arxiv.org/schemas/atom">Department of Physics</arxiv:affiliation>
4. </author>

现在，我可以像下面一样轻松地在Kotlin中创建一个 Author 数据类，而无需第三行

Author.kt

@Parcelize
data class Author(
    var name: String = ""
) : Parcelable

我必须为Author标记生成数据类的唯一问题是xml文件上方代码的第三行。我真的不知道如何转换第三行

<arxiv:affiliation xmlns:arxiv="http://arxiv.org/schemas/atom">Department of Physics</arxiv:affiliation>

进入Kotlin数据类

就像上面的第三行一样，我们也有

<opensearch:totalResults xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/">161478</opensearch:totalResults>
<opensearch:startIndex xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/">0</opensearch:startIndex>
<opensearch:itemsPerPage xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/">2</opensearch:itemsPerPage>

所以，我的问题摘要是，如何将这类xml代码转换为Kotlin数据类？预先感谢。
