XML syntax highlighting for Zed.
This extension only claims .xml by default, plus any file whose first line matches an XML declaration (^<.*xml). There are too many XML based formats to hardcode them all, so extra extensions are left to you.
To associate more file types, add them to your Zed settings.json:
{
"file_types": {
"XML": ["*.svg", "*.xsl", "*.dtd"]
}
}
