error when writing xml path for path with colon

[ghost]

Not sure it's a bug in me or the software.

I have a job:

name: 21_SwimSwam News - Time Standard
url: "https://swimswam.com/feed/#1"
filter:
   - xpath:
      method: xml
      path: '//item/title/text()|//item/description/text()'
      exclude: 'a'
   - html2text:
      method: bs4
   - keep_lines_containing:
      re: '(?i)usa\sswimming|time\sstandard|ruta'
   - re.sub: '(?m)^[ \t]*'
additions_only: true

According to the docs I should be able to add this line to the path but I get an error.

//item/content:encoded/text() path: '//item/title/text()|//item/description/text()|//item/content:encoded/text()'

https://webchanges.readthedocs.io/en/stable/filters.html?highlight=RSS#using-css-and-xpath-filters-with-xml-and-exclusions

Seems I am having an issue with the colon.

Hmmm... Its Either YAML or some legacy code; I'll look into it.

Can you please run the job with '--verbose' and paste at least the top lines (with version and system info) and the full traceback and error message?

Didn't realize from mobile that you posted the complete job. The error I got is

    selected_elems = root.xpath(self.expression, namespaces=self.namespaces)
  File "src\lxml\etree.pyx", line 1597, in lxml.etree._Element.xpath
  File "src\lxml\xpath.pxi", line 305, in lxml.etree.XPathElementEvaluator.__call__
  File "src\lxml\xpath.pxi", line 225, in lxml.etree._XPathEvaluatorBase._handle_result
lxml.etree.XPathEvalError: Undefined namespace prefix

I don't know XML, but a Google search led me to https://stackoverflow.com/questions/44188237/python-parse-xml-feed-error-xpathevalerror-undefined-namespace-prefix which indicates that you probably need to define namespaces; the sub-directive namespaces is documented here https://webchanges.readthedocs.io/en/stable/filters.html#css-and-xpath.

Not knowing XML I really can't help you further, but hope to have pointed you to the right direction!

That was it... thanks for pointing me in the right direction.

working job below:
