parsing choice sequence loses element ordering

martaver commented 5 years ago

Trying to parse an XML file with a schema that contains a choice sequence:

      <xs:choice minOccurs="1" maxOccurs="unbounded">
        <xs:element name="Title" type="xs:string" />
        <xs:element name="Subtitle" type="xs:string" />
        <xs:element name="Html" type="xs:string" />
        <xs:element name="Vimeo" type="VimeoPart" />
        <xs:element name="Youtube" type="YoutubePart" />
        <xs:element name="Soundcloud" type="SoundcloudPart" />
        <xs:element name="Image" type="ImagePart" />
        <xs:element name="Link" type="LinkPart" />
      </xs:choice>

The above generates the following in a type:

        Html: string[];
    Image: ImagePart[];
    Link: LinkPart[];
    Soundcloud: SoundcloudPart[];
    Subtitle: string[];
    Title: string[];
    Vimeo: VimeoPart[];
    Youtube: YoutubePart[];

However, this structure loses the ordering of the elements. In my case, order is important because it contains site content.

I would have expected the following types, perhaps:

choices: (Html | Image | Link | Soundcloud | Subtitle | Title | Vimeo | Youtube)[]

Unfortunately, I noticed this severe limitation several months ago when looking for a data binding tool for TypeScript. I never did find a suitable one comparable to, say, Java JAXB. Also, I think this project has been abandoned. There was mention of a rewrite of cxml but I never heard back about its status: https://github.com/charto/cxml/issues/15

Is there really no comprehensive xsd/xml parser/writer for typescript out there?
