Examples of net.htmlparser.jericho.Renderer

net.htmlparser.jericho.Renderer
ozilla.com/thunderbird/">Mozilla Thunderbird and other email clients provide an automatic conversion of HTML content to text in their alternative MIME encoding of emails.
The output using default settings complies with the "text/plain; format=flowed" (DelSp=No) protocol described in RFC3676.
Many properties are available to customise the output, possibly the most significant of which being {@link #setMaxLineLength(int) MaxLineLength}. See the individual property descriptions for details.
Use one of the following methods to obtain the output:
- {@link #writeTo(Writer)}
- {@link #appendTo(Appendable)}
- {@link #toString()}
- {@link CharStreamSourceUtil#getReader(CharStreamSource) CharStreamSourceUtil.getReader(this)}
The rendering of some constructs, especially tables, is very rudimentary. No attempt is made to render nested tables properly, except to ensure that all of the text content is included in the output.
Rendering an entire {@link Source} object performs a {@linkplain Source#fullSequentialParse() full sequential parse} automatically.
Any aspect of the algorithm not specifically mentioned here is subject to change without notice in future versions.
To extract pure text without any rendering of the markup, use the {@link TextExtractor} class instead.
