Minor Description
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 wold 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?
