XML with multiple fields to Elastic Search

[rogueleader]

Hi, I am a newbie to ELK and have been browsing these forums and other tutorials in search of some comprehensive guide for handling XML files.Now most of the examples i saw are handling simple XMLs ( and pretty small ones ).

Basically my aim is to load up some big XML file data to ElasticSearch. Here's a small part of one of my XMLs :

<AbstractText>We have reproduced the experiment of acoustic monitoring of spontaneous popping of single soap bubbles standing in air reporte
d by Ding et al. [2aaPhys. Rev. E 75, 041601 (2007)]. By using a single microphone and two different signal acquisition systems recording in parallel 
the signal at the microphone output, among them the system used by Ding et al., we have experimentally evidenced that the acoustic precursors of bubble popping events detected by Ding et al. actually result from an acausal artifact of the signal processing performed by their acquisition system which lies outside of its prescribed working frequency range. No acoustic precursor of popping could be evidenced with the microphone used in these experiments, whose sensitivity is 1VPa-1 and frequency range is 500 Hz-100 kHz.</AbstractText>

• So kindly suggest me best possible way to handle these files.
• Do i have to manually specify all the fields in filter or Is there any shortcut ( using dtd ? ) ?
• How to handle multiple fields , for example : AuthorList has multiple authors.

Please guide me in the right direction. Thanks for any help!
