Dialect differences
Both XML and CSV are file formats, so what differs below is how each one chooses to represent a value.
| Property | in XML | in CSV |
|---|---|---|
| identifiers | Attribute values in quotes; entities (& < >) for ... | Double quotes; a literal quote is doubled ("" ) |
| dates | Text (xs:date / xs:dateTime when an XSD is in play) | Conventional text: 2026-09-18 or 2026-09-18 14:30:00 |
| binary | base64Binary / hexBinary inside text | Not supported |
| separator | Tags, not delimiters | Comma "," |
| encoding | Declared in the XML declaration | No declaration - UTF-8 works only with a BOM |
| typing | None in the markup itself | None - every field is text |
| shape | Arbitrary tree | Flat table, optional header row |
| ceiling | Whole document is usually parsed into memory | No formal limit; row count bounded by memory |
