+  Handle malformed XML in lxml iterparse with recover mode. Use when:
+  (1) lxml.etree.XMLSyntaxError "AttValue: ' expected" or similar parse errors on
+  large XML files like Apple Health exports, (2) need streaming XML parsing that
+  tolerates broken attributes, (3) tried passing parser=XMLParser(recover=True)
+  to iterparse and got "unexpected keyword argument 'parser'". The recover flag
+  is a direct parameter of iterparse, not passed via a parser object.

+# lxml iterparse: Recovering from Malformed XML
+
+## Problem
+Large XML files (e.g., Apple Health exports) sometimes contain malformed attribute
+values with unescaped characters. lxml's `iterparse` raises `XMLSyntaxError` and
+aborts parsing, losing all data after the corrupt element.
+
+## Context / Trigger Conditions
+- Parsing large XML files with `lxml.etree.iterparse`
+- Error: `lxml.etree.XMLSyntaxError: AttValue: ' expected, line NNNN, column NNN`
+- The malformed XML is from an external source you can't control (Apple Health, etc.)
+- You want to skip corrupt elements and continue parsing
+
+## Solution
+Pass `recover=True` directly to `iterparse` — it's a first-class parameter:
+
+```python
+from lxml import etree
+
+context = etree.iterparse(
+    file_path,
+    events=("end",),
+    tag=("Record", "Workout"),
+    recover=True,  # Skip malformed elements instead of aborting
+)
+```
+
+**Common mistake**: Trying to pass a parser object:
+```python
+# WRONG — iterparse does NOT accept a parser= keyword
+parser = etree.XMLParser(recover=True)
+context = etree.iterparse(file_path, parser=parser)
+# TypeError: __init__() got an unexpected keyword argument 'parser'
+```
+
+## Verification
+Parse the full file without `XMLSyntaxError`. Check `context.error_log` after
+parsing to see which elements were skipped.
+
+## Notes
+- `recover=True` defaults to `True` for HTML mode, `False` for XML mode
+- Recovered elements may have missing or truncated attributes — always validate
+  parsed values before using them
+- Other useful iterparse flags: `huge_tree=True` for very deep/large documents
+- The full list of iterparse parameters can be viewed with `help(etree.iterparse)`
