I have component for rendering SVG icon:
import {Component, Directive} from 'angular2/core'; import {COMMON_DIRECTIVES} from 'angular2/common'; @Component({ selector: '[icon]', directives: [COMMON_DIRECTIVES], template: `<svg role="img" class="o-icon o-icon--large"> <use [xlink:href]="iconHref"></use> </svg>{{ innerText }}` }) export class Icon { iconHref: string = 'icons/icons.svg#menu-dashboard'; innerText: string = 'Dashboard'; }
This triggers error:
EXCEPTION: Template parse errors: Can't bind to 'xlink:href' since it isn't a known native property ("<svg role="img" class="o-icon o-icon--large"> <use [ERROR ->][xlink:href]=iconHref></use> </svg>{{ innerText }}"): SvgIcon@1:21
How do I set dynamic xlink:href
?
SVG elements doen't have properties, therefore attribute binding is required most of the time (see also Properties and Attributes in HTML).
For attribute binding you need
<use [attr.xlink:href]="iconHref">
or
<use attr.xlink:href="{{iconHref}}">
Update
Sanitization might cause issues.

Update DomSanitizationService
is going to be renamed to DomSanitizer
in RC.6
Update this should be fixed
but there is an open issue to support this for namespaced attributes https://github.com/angular/angular/pull/6363/files
As work-around add an additional
xlink:href=""
Angular can update the attribute but has issues with adding.
If xlink:href
is actually a property then your syntax should work after the PR was added as well.
