I am using the Tika 1.19 as a GUI to extract metadata from an .mp3 file. The
sample rate is available and I am able access it, but only as a string or as
part of a JSON document. I am working in XML and would like to use XML as a
content handler. But when the metadata is returned as ‘structured text’ (XML)
the sample rate is not returned. I have tried using Tika 1.19 in a Maven
project and experimented with different contentHandlers and the same issue
occurs. I cannot seem to get the sample rate returned in an XML doc, but I am
able to access the data from the metadata object itself. If the metadata is
returned as a string, the sample rate is there, if it is returned as XML, the
sample rate is not returned. I am wondering what I am doing wrong or
misunderstanding. Perhaps an issue with the parser or contentHandler that is
used?
