Body
I need to find the dates within a string and their positions. Consider the example string "The interesting date is 4 days from today and it is 20th july of this year, another date is 18th Feb 1997" I need the output (Assuming today is 2013-07-14) 2013-07-17, position 25 2013-07-20, position 56 1997-02-18, position 93 I have managed to write the code to get the various parts of the string that is recognized as date. Need to enhance/change this to achieve the above output. Any hints or help is appreciated: <pre><code> Properties props = new Properties(); AnnotationPipeline pipeline = new AnnotationPipeline(); pipeline.addAnnotator(new PTBTokenizerAnnotator(false)); pipeline.addAnnotator(new WordsToSentencesAnnotator(false)); pipeline.addAnnotator(new POSTaggerAnnotator(false)); pipeline.addAnnotator(new TimeAnnotator("sutime", props)); Annotation annotation = new Annotation("The interesting date is 4 days from today and it is 20th july of this year, another date is 18th Feb 1997"); annotation.set(CoreAnnotations.DocDateAnnotation.class, "2013-07-14"); pipeline.annotate(annotation); List<CoreMap> timexAnnsAll = annotation.get(TimeAnnotations.TimexAnnotations.class); timexAnnsAll.each(){ println it } </code></pre> With the above code I get the output as: 4 days from today 20th july of this year 18th Feb 1997 EDIT:: Managed to get the date part, with the following change <pre><code>timexAnnsAll.each(){it -> Timex timex = it.get(TimeAnnotations.TimexAnnotation.class); println timex.val + " from : $it" } </code></pre> Now the output is: 2013-07-18 from : 4 days from today 2013-07-20 from : 20th july of this year 1997-02-18 from : 18th Feb 1997 All I need to solve now is to find the position of the date within the original string.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
