    Nope, sorry, it's just an XML generator. The Python stdlib offers https://docs.python.org/3/library/xml.etree.elementtree.html and PyPI offers https://github.com/martinblech/xmltodict for parsing, and you could write CSV with csvwriter or pandas.
  • Like JQ, but for HTML

    xmlstarlet is really nothing like jq, as a language. But yes, I use it because it is the best commandline xml processor I'd found. That's the only similarity to jq.

    Is this the yq? https://kislyuk.github.io/yq/ It does contain an 'xq', as a literal wrapper for jq, piping output into it after transcoding XML to JSON using xmltodict https://github.com/martinblech/xmltodict (which explodes xml into separate JSON data structures).

    This is a bash one-liner! But TBF it really is a 'jq for xml'. I think it would be horrible for some things, but you could also do a lot of useful things painlessly.

    Parsel is a library build to extract data from XML/HTML documents with XPath and CSS selectors support, and could be combined with regular expressions. It's usees lxml parser under the hood by default.

    So, now that I no longer work in that industry, and I had some free time, I created a lazy parsing package using lxml instead of the xml parser in the standard library, which can help people who want to have a python only parsing solution.

  • Parsing XML file deletes whitespace. How to avoid it?

    I got curious about this now so I did some tests on my own, and it appears that the XML parser implementation in Python does indeed strip all newline characters from attributes. Whether this is according to XML standard I do not know; I also briefly tried an alternative XML implementation for Python and it behaves the same, so I would assume that this is standard behavior, but I'm not knowledgable enough about XML to say for certain.
  • Use case for ETL over ELT?

    I use lxml for the XML parsing and pyodbc as the ODBC library. We have a small team so I just keep it as simple as possible: 1. A cursor yields the XML documents from a SQL query as a stream 2. A generator function parses the XML document and yields the rows (you could parallelize this step) 3. Stream each of the resulting rows to a single CSV file 4. Scoop up the resulting CSV file into the target database (usually with the DB engine's loader; bulk insert isn't so fast over ODBC) It ends up being a straight forward, low-overhead approach.

    Generally, I'm already using Python to glue together things like OpenCV or libxml, which do the heavy-lifting, and taking advantage of how things like Qt's QImage release Python's Global Interpreter Lock, allowing me to load and process images on a background thread, so the Python code itself is usually already I/O-bound, but yes. If the Python code would become a bottleneck, it helps with that too.

    lxml is an XML parser however, it also supports HTML parsing. It's blazing fast and supports XPath. I think it isn't as beginner friendly to use, though it has detailed documentation. It works less well with heavily broken HTML documents and the encoding detection isn't as good as the one of BS4.

    According to lxml benchmarking docs, Python’s built in xml parser wouldn’t behave that bad either: https://github.com/lxml/lxml/blob/master/doc/performance.txt
