Repro steps

• in index.html, use the i18n marker like

  please wait...

• run ng xi18n
• the 'please wait' does not popup in the gererated .xlf files
• run ng build ng build -prod --aot --output-path=dist/de --base-href /de/ --i18n-file=src/i18n/messages.de.xlf --i18n-format=xlf --locale=de;

ng xi18n operates over components of your Angular application, but index.html is not part of it actually. It's not a component template.

I don't think this is functionality we can provide but @ocombe might know more.

[areijngoudt]

wel, the entry and name index.html are in the .angular-cli.json. Also, the cli can inject the base href using the --base-href switch

[ocombe]

it will be possible as part of universal (it's on the roadmap)

If I can't use server-side rendering, is there a plan to inject translated string in index.html or other static file ?

[bettysteger]

if parsing the index.html would be possible, we could also set the right language attribute in the HTML-tag.

What's the status on this? I'm trying to set up locale-specific index.html to change some tags specific to the locale, like the title, the HTML lang attribute, canonical link, and others, but can't rely on the i18n translation.

Was trying to make multiple index.html files, 1 per locale, but when I run with --localize flag it ignores the angular.json config about which index.html to use.

Looks like this, building with --configuration=es-CO works, but using --localize to build all locales at once doesn't work:

I filed a bug for this: #17684
