Method Detail

sanitize

public static void sanitize(@Nullable
                            String html,
                            HtmlSanitizer.Policy policy)

Sanitizes the given HTML by applying the given policy to it.

This method is not in the TCB.

This method has no return value since policies are assumed to render things they accept and do nothing on things they reject. Use HtmlStreamRenderer to render content to an output buffer.

Parameters:

html - A snippet of HTML to sanitize. null is treated as the empty string and will not result in a NullPointerException.

policy - The Policy that will receive events based on the tokens in HTML. Typically, this policy ends up routing the events to an HtmlStreamRenderer after filtering. HtmlPolicyBuilder provides an easy way to create policies.

sanitize

public static void sanitize(@Nullable
                            String html,
                            HtmlSanitizer.Policy policy,
                            HtmlStreamEventProcessor preprocessor)

Sanitizes the given HTML by applying the given policy to it.

This method is not in the TCB.

This method has no return value since policies are assumed to render things they accept and do nothing on things they reject. Use HtmlStreamRenderer to render content to an output buffer.

Parameters:

html - A snippet of HTML to sanitize. null is treated as the empty string and will not result in a NullPointerException.

policy - The Policy that will receive events based on the tokens in HTML. Typically, this policy ends up routing the events to an HtmlStreamRenderer after filtering. HtmlPolicyBuilder provides an easy way to create policies.

preprocessor - A processor that may wrap the policy to reinterpret parse events. Since the policy encapsulates its output buffer, this is not in the policy's TCB.
