Hello,
now I like to get the begin and end offset of each links in wikitext.
Later maybe other components (images).
Is that possible to do this using Mylyn WikiText?
I tried to use getLocator().getDocumentOffset() in method:
void
org.eclipse.mylyn.wikitext.core.parser.builder.NoOpDocumentBuilder.link(Attributes
attributes, String hrefOrHashName, String text) and
void
org.eclipse.mylyn.wikitext.core.parser.builder.NoOpDocumentBuilder.characters(String
text)
but I found out that document offset is not updated after calling method
link(Attributes attributes, String hrefOrHashName, String text).
The offset is also sometimes decremented. So far I now, it should be
only incremented.
I test by using this simple text below as my MediaWiki WikiText:
The '''EditorX''' is an [[text editor|editor]] of small to
medium-sized [[text]].
This is a [[test]] too ('''yes''').
_*The Result*_*:*
*Offset
* *Component type
* *Value
* *Comment*
-1 DOCUMENT_BEGIN
[]
0 BLOCK_BEGIN
[PARAGRAPH]
0 CHARACTERS_GROUP [*The *]
4 SPAN_BEGIN [BOLD]
7 CHARACTERS_GROUP [*EditorX*]
7 SPAN_END [BOLD]
17 CHARACTERS_GROUP [* is an *]
*7*
LINK [*editor*] The offset is anyhow decremented (¿*Bug*?)
7
CHARACTERS_GROUP [* of small to medium-sized *] Now is all offset
incorrect
55 LINK
[*text*]
55 CHARACTERS_GROUP [*.*]
*83* CHARACTERS_GROUP [] New line position is correct now.
83 CHARACTERS_GROUP [*This is a *]
93 LINK [*test*]
*93* CHARACTERS_GROUP [* too (*] 93 is offset of the link
*107* SPAN_BEGIN [BOLD] Here is correct again
110 CHARACTERS_GROUP
[*yes*]
110 SPAN_END [BOLD]
116 CHARACTERS_GROUP [*).*]
118 BLOCK_END [PARAGRAPH]
118 DOCUMENT_END []
For heading I am currently using:
getLocator().getLineDocumentOffset() for beginOffset and
getLocator().getLineDocumentOffset()+getLocator().getLineLength()
for endOffset
and it works so far.
It does not work for link because there can be some links in the same line.
Best regards,
Luven

Thank you David,
that is the functionality I need. I've tried also with headings and
images.
And it works too.
Best regards,

You want to do something like this:
public class ExtractHyperlinksBuilder extends NoOpDocumentBuilder {
private Set<String> hyperlinks = new HashSet<String>();
@Override
public void link(Attributes attributes, String hrefOrHashName, String
text) {
hyperlinks.add(hrefOrHashName);
}
@Override
public void imageLink(Attributes linkAttributes, Attributes
imageAttributes, String href, String imageUrl) {
hyperlinks.add(href);
}
public Set<String> getHyperlinks() {
return hyperlinks;
}
}
MarkupParser parser =
new MarkupParser(ServiceLocator.getInstance().getMarkupLanguage("MediaWiki"));
ExtractHyperlinksBuilder builder = new ExtractHyperlinksBuilder();
parser.setBuilder(builder);
Reader markupContent = null;// open reader
try {
parser.parse(markupContent);
} finally {
markupContent.close();
}
// do something with builder.getHyperlinks()
Regards,
David

Hello everyone,
I am a new Mylyn user. I'm planning to work with Wiki Articles
with java and eclipse.
Is that possible to extract attributes like hyperlinks, headings,
images, etc. directly from e. g. wikimedia markup-language using
WikiText.
like:
- obj.getHyperlinks();
If it is possible or maybe there is solutions for this, how could
it be done?
Thank you and best regards
Luven
