switch

<switch>

The <switch> SVG element evaluates the requiredFeatures, requiredExtensions and systemLanguage attributes on its direct child elements in order, and then processes and renders the first child for which these attributes evaluate to true. All others will be bypassed and therefore not rendered. If the child element is a container element such as a <g>, then the entire subtree is either processed-rendered or bypassed-not rendered-

Note that the values of properties display and visibility have no effect on switch element processing- In particular, setting display to none on a child of a switch element has no effect on true-false testing associated with switch element processing-

SVG <switch> example

This example demonstrates showing different text content depending on the browser's language settings. The switch element will display the first of its child elements whose systemLanguage attribute matches the user's language, or the element with no systemLanguage attribute if none of them matches.
