URL: https://github.com/apache/datafusion-sqlparser-rs/issues/1816
Postgres, db2, and oracle all support the `xmltable` table-valued function.
```sql
SELECT xmltable.*
FROM xmldata,
XMLTABLE('//ROWS/ROW'
PASSING data
COLUMNS id int PATH '@id',
ordinality FOR ORDINALITY,
"COUNTRY_NAME" text,
country_id text PATH 'COUNTRY_ID',
size_sq_km float PATH 'SIZE[@unit = "sq_km"]',
size_other text PATH 'concat(SIZE[@unit!="sq_km"], " ",
SIZE[@unit!="sq_km"]/@unit)',
premier_name text PATH 'PREMIER_NAME' DEFAULT 'not specified');
```
Currently, sqlparser fails to parse it with the following error: `Expected:
), found: PASSING`
