Hello dear maintainers
I'm trying to learn to use crate ethercat, but having an issue with the ESI XML files
I'm trying to run ethercat/examples/cyclic-data.rs but the XML parsing fails with my ESI files
I tried the following files: xml.zip
- omron 1S, ESI file
- tinsmith erob, ESI file
both work well on the sysmac-studio software, so I doubt there is something wrong about the files themselves. They both give the same parser errors when loaded by ethercat-esi
$ target/debug/examples/cyclic-data ~/omron-1s.xml
Error: Custom { kind: Other, error: "Syntax: 1:1 Unexpected characters outside the root element: \u{feff}" }
$ target/debug/examples/cyclic-data ~/tinsmith-erob.xml
Error: Custom { kind: Other, error: "Syntax: 1:1 Unexpected characters outside the root element: \u{feff}" }\u{feff} is a character that marks the file as utf-8, so it should be considered as whitespace. I added it to is_whitespace_char() in xml-rs
Then I fall into a new error
$ target/debug/examples/cyclic-data ~/omron-1s.xml
Error: Custom { kind: Other, error: "custom: duplicate field `Name`" }It seems that ethercat-esi doesn't handle locale variants in xml files, so I removed the duplicates and run again to get the following error
$ target/debug/examples/cyclic-data ~/omron-1s.xml
Error: Custom { kind: Other, error: "custom: missing field `Vendor`" }
$ target/debug/examples/cyclic-data ~/tinsmith-erob.xml
Error: Custom { kind: Other, error: "custom: missing field `Sm`" }The fields mentionned are not missing in the xml files, so I don't know what is wrong.
I tried to fix ethercat-esi by switching it from serde-xml-rs to quick-xml, but it gave me the same kind of error as the latest ones, as we can see on this issue
Is there a way to fix all these issues from ethercat-esi (especially the missing fields) ?
