Verified usage

Verified import paths — ran on the pinned version, not inferred.

parse_xml

✓ from meld3 import parse_xml

✗ import meld3; meld3.parse_xml

Generally used as a direct import to avoid namespace confusion.

Parse an XML template with Genshi-like directives and render it with context data.

from meld3 import parse_xml template = '<html xmlns:py="http://genshi.edgewall.org/"><body><h1 py:content="title">Title</h1></body></html>' tree = parse_xml(template) tree.expand({'title': 'Hello, World!'}) result = tree.write() print(result)

Debug

Known issues

deprecatedmeld3 is effectively unmaintained and deprecated. It is only used internally by old versions of Supervisor. Consider switching to alternatives like Jinja2 or Tempita.

fix

Replace with Jinja2 or another modern templating engine.

affects: >=2.0.0

gotchameld3 parses XML templates and uses Genshi-like attribute directives (py:attrs, py:content, etc.). It does NOT support Genshi's full syntax; only a limited subset.

fix

Use only the documented directives: py:content, py:attrs, py:replace, py:if, py:for, py:strip.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'meld3'

meld3 is not installed, or trying to import from a virtual environment where pip install did not run.

fix

Run `pip install meld3`

AttributeError: module 'meld3' has no attribute 'parse_xml'

Old code using import meld3 and calling meld3.parse_xml, but parse_xml is a top-level function.

fix

Use `from meld3 import parse_xml` instead.
