Wikitext OutlineItem: how can I get the heading text? [message #1684392]

We are using wikitext with mediawiki syntax, and try to get the original text of a heading from its OutlineItem.

I see two options, both of which have some limitation:
- getLabel(): looks good, but "could be truncated"
- getId(): seems to contain everything but decoding it difficult.

So far we are using getId() and decode in two steps:
- replace all '.' by '%'
- use URLDecoder.decode()

This actually worked fine, until we hit the first occurrence of '.' in an original heading. We could not find a way to distinguish a genuine '.' from the start of an escape sequence.

Is there a solution that avoids both limitations?
thanks
Stephan

Stephan,

Are you using the OutlineParser programatically? If so, truncation can be controlled using OutlineParser.setLabelMaxLength(). By default truncation does not occur, so as long as you're not setting a maximum length you should be in good shape.

Encoding of a heading ID is one-way and lossy, so not a good option to get the original heading text.

I hope that helps,

David
