Mel Martinez commented on PDFBOX-521:
-------------------------------------
I have no strong feelings about the correct 'name' to use for this patch.
'LogicalTextStripper' isn't quite on the mark since it is still just using
geographic landmarks to derive breaks, though it is guessing at certain common
patterns used for logical structure (ex> hanging indents). But to actuall
call it 'LogicalTextStripper' seem way too ambitious for what it does and might
scare people from trying to use it.
Technically, it can be made (through the control options) to behave like the
current PDFTextStripper so it *could* simply replace it. However its default
behavior is different so I don't know if that would break anyone who depends on
the current stripper behavior.
How about "PDFStructuredTextStripper" ? It does try to retain the
page/article structure of the document, as well as extracting the paragraphs.

> URL: https://issues.apache.org/jira/browse/PDFBOX-521
> Project: PDFBox
> Issue Type: Improvement
> Components: Parsing
> Affects Versions: 0.8.0-incubator
> Environment: all
> Reporter: Mel Martinez
> Attachments: pdftextstripper2.zip

>
> The current behavior of the org.apache.pdfbox.util.PDFTextStripper class is
> to ignore paragraph demarcation in the text. It basically just renders each
> line of text as it discovers it, separating each line equally with the same
> line separator.
> This makes it difficult to identify paragraph (or even page) starts and stops
> in the extracted text. This is often necessary for text processing that
> needs to work with logical 'chunks' of text. Further, rendering into other
> formats (such as HTML or XML) is facilitated by resolving the document into
> more discrete logical text chunks.
> The request here is for improved text extraction that provides more discrete
> instrumentation of the parsing, allowing one to identify / tag paragraph
> starts and stops.
