Android Kotlin Retrofit + SimpleXMLConverter ElementList解析不正确

Question

我正在尝试解析一些podcast xml提要，但无法获得所有类别和具有相同名称的其他多个字段。

提要示例：http://demo3984434.mockable.io/cast

<rss xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd" xmlns:itunesu="http://www.itunesu.com/feed" xmlns:media="http://search.yahoo.com/mrss/" version="2.0">
    <channel>
        <title>Podcast Title</title>
        <link>http://link.com</link>
        <language>en-us</language>
        <itunes:subtitle>Subtitle!!!</itunes:subtitle>
        <itunes:author>Author Name</itunes:author>
        <media:category scheme="http://www.itunes.com/dtds/podcast-1.0.dtd">Comedy</media:category>
        <media:category scheme="http://www.itunes.com/dtds/podcast-1.0.dtd">Society &amp; Culture</media:category>
        <media:category scheme="http://www.itunes.com/dtds/podcast-1.0.dtd">Games &amp; Hobbies/Video Games</media:category>
        <media:category scheme="http://www.itunes.com/dtds/podcast-1.0.dtd">TV &amp; Film</media:category>
        <media:category scheme="http://www.itunes.com/dtds/podcast-1.0.dtd">Music</media:category>
        <itunes:category text="Comedy"/>
        <itunes:category text="Society &amp; Culture"/>
        <itunes:category text="Games &amp; Hobbies"/>
        <itunes:category text="Video Games"/>
        <itunes:category text="TV &amp; Film"/>
        <itunes:category text="Music"/>
    </channel>
</rss>

RSSFeed.kt：

@Root(name = "rss", strict = false)
class RSSFeed {

    @field:Element(name = "channel")
    var mFeedChannel: FeedChannel? = null
}

FeedChannel.kt

@Root(name = "channel", strict = false)
open class FeedChannel {

    @field:Element(name = "title")
    var mTitle: String? = null

    @field:Element(name = "link")
    var mLink: String? = null

    @field:Element(name = "subtitle")
    var mSubtitle: String? = null

    @field:Element(name = "author")
    var mAuthor: String? = null

    @field:ElementList(entry = "category", inline = true)
    var mCategories: List<Category>? = null

    @Root(name = "category", strict = false)
    class Category {

        @field:Element(name = "category")
        var category: String? = null
    }
}

但类别列表元素始终为空：

找到解决方案：

更改了@field:Element字段，并使用String代替另一个类Category。感谢@DaveThomas

@Root(name = "channel", strict = false)
class FeedChannel {

    @field:Element(name = "title")
    var mTitle: String? = null

    @field:Element(name = "link")
    var mLink: String? = null

    @field:Element(name = "subtitle")
    var mSubtitle: String? = null

    @field:Element(name = "author")
    var mAuthor: String? = null

    @field:ElementList(entry = "category", type = String::class, inline = true)
    var mCategories: List<String>? = null

}
