Update documents with XML data

update_xml(
  conn,
  files,
  name,
  commit = TRUE,
  optimize = FALSE,
  max_segments = 1,
  expunge_deletes = FALSE,
  wait_searcher = TRUE,
  soft_commit = FALSE,
  prepare_commit = NULL,
  wt = "json",
  raw = FALSE,
  ...
)

`conn`	A solrium connection object, see SolrClient
`files`	Path to a single file to load into Solr
`name`	(character) Name of the core or collection
`commit`	(logical) If `TRUE`, documents immediately searchable. Deafult: `TRUE`
`optimize`	Should index optimization be performed before the method returns. Default: `FALSE`
`max_segments`	optimizes down to at most this number of segments. Default: 1
`expunge_deletes`	merge segments with deletes away. Default: `FALSE`
`wait_searcher`	block until a new searcher is opened and registered as the main query searcher, making the changes visible. Default: `TRUE`
`soft_commit`	perform a soft commit - this will refresh the 'view' of the index in a more performant manner, but without "on-disk" guarantees. Default: `FALSE`
`prepare_commit`	The prepareCommit command is an expert-level API that calls Lucene's IndexWriter.prepareCommit(). Not passed by default
`wt`	(character) One of json (default) or xml. If json, uses `fromJSON` to parse. If xml, uses `read_xml` to parse
`raw`	(logical) If `TRUE`, returns raw data in format specified by `wt` param
`...`	curl options passed on to `HttpClient`

You likely may not be able to run this function against many public Solr services, but should work locally.
