Error when parsing a field which was not present in the xsd file

[davidspiess]

If the parser (v.0.1.1) encounters a field which is not part of the xsd, it throws the following error

Unhandled rejection TypeError: Cannot read property 'proxy' of undefined

If my xml provider adds a new field to their api my whole application breaks until i regenerate the xsd with cxsd.

I noticed it's not possible to create a pull request for a specific commit or release so i forked the repository and fixed it for my project.

@davidspiess Maybe here is not the best place to ask, but since you are using cxsd, do you have any doc on how to use it with cxml? I've tried to infer how to use them with their TS typings, but so far, no luck.

Thanks!

[davidspiess]

I used the 0.1.1 version as there is documentation for that https://github.com/charto/cxml/tree/fce69086cd5f7ec476e0ff87d5a7f44b9879bd69

You have to pass the output of cxsd as second parameter to the parser.

import * as cxsd from 'cxsd/outputfiles';

const parser = new cxml.Parser();
parser.parse('<xml></xml>', cxsd.document);

[Ottunger]

Thanks a lot :) Indeed .parse does not exist on the object according to TS.

So you're using a custom cxml, makes sense. Is it a fork of 0.1.1?

[davidspiess]

Always glad to help! 😄 Yeah i created a fork of 0.1.1 because of the issue which i described above.
