Package org.apache.tika.parser.html

Interface HtmlMapper

  • All Known Implementing Classes:
    DefaultHtmlMapper, IdentityHtmlMapper
    public interface HtmlMapper
    HTML mapper used to make incoming HTML documents easier to handle by Tika clients. The HtmlParser looks up an optional HTML mapper from the parse context and uses it to map parsed HTML to "safe" XHTML. A client that wants to customize this mapping can place a custom HtmlMapper instance into the parse context.
    Since:
    Apache Tika 0.6

    • Method Detail

      • mapSafeElement

        String mapSafeElement​(String name)
        Maps "safe" HTML element names to semantic XHTML equivalents. If the given element is unknown or deemed unsafe for inclusion in the parse output, then this method returns null and the element will be ignored but the content inside it is still processed. See the isDiscardElement(String) method for a way to discard the entire contents of an element.
        Parameters:
        name - HTML element name (upper case)
        Returns:
        XHTML element name (lower case), or null if the element is unsafe

      • isDiscardElement

        boolean isDiscardElement​(String name)
        Checks whether all content within the given HTML element should be discarded instead of including it in the parse output.
        Parameters:
        name - HTML element name (upper case)
        Returns:
        true if content inside the named element should be ignored, false otherwise

      • mapSafeAttribute

        String mapSafeAttribute​(String elementName,
                        String attributeName)
        Maps "safe" HTML attribute names to semantic XHTML equivalents. If the given attribute is unknown or deemed unsafe for inclusion in the parse output, then this method returns null and the attribute will be ignored. This method assumes that the element name is valid and normalised.
        Parameters:
        elementName - HTML element name (lower case)
        attributeName - HTML attribute name (lower case)
        Returns:
        XHTML attribute name (lower case), or null if the element is unsafe
