Bug Report: XML Parsing is not working correctly

[tlfish1510]

I work on the NOAA CMR program. We use repository https://git.services.nesdis.noaa.gov/dissemination/catalog/cmr-repos/dev-cmr-base, and periodically migrate changes from this repository to it, in order to capture changes you make into ours.

I recently migrated the changes in this repository up to tag CMR-1.287.0-r25.4.2 (previous migration point was CMR-1.277.0-r25.2.5). Prior to the migration I was able to ingest our sample NOAA ISO file into CMR without issue. Now that I have migrated the latest code I am no longer able to ingest that same ISO file into CMR.

At first it appeared that the issue was that the warnings I was seeing became errors, but as it turns out the UMM-C object being derived by the code after the migration varies from what is derived from the code prior to the migration.

I am attaching the UMM-C objects that were generated along with the ISO I ingested:
GOES_ABI_L1B_RAD.xml - the ingested ISO
prior-UMM-C.json - the object generated from the pre-migration code
after-UMM-C.json - the object generated from the after-migration code

The variances are found within the RelatedUrls. ArchiveAndDistributionInformation and Platforms fields of the UMM-C object. In the 1st 2 fields, the specific variance is on the Format field. In the last field the pre-migration object had 3 platforms while the after-migration object lacked any.

The xpaths used in our code to obtain the Format field are:

• /gmi:MI_Metadata/gmd:distributionInfo/gmd:MD_Distribution/gmd:distributor/gmd:MD_Distributor/gmd:distributorFormat/gmd:MD_Format/gmd:name/gco:CharacterString
• /gmi:MI_Metadata/gmd:distributionInfo/gmd:MD_Distribution/gmd:distributionFormat/gmd:MD_Format/gmd:name/gco:CharacterString

The xpaths used in our code to obtain the Platforms field are:

• /gmi:MI_Metadata/gmd:identificationInfo/gmd:MD_DataIdentification/gmd:descriptiveKeywords/gmd:MD_Keywords
• /gmi:MI_Metadata/gmi:acquisitionInformation/gmi:MI_AcquisitionInformation/gmi:platform/gmi:MI_Platform, and within this xpath: gmi:instrument/gmi:MI_Instrument

after-UMM-C.json
GOES_ABI_L1B_RAD.xml
prior-UMM-C.json
