Corrupt an XML File Online
Corrupt an .xml file online for free. Breaks the declaration, tag nesting and encoding so XML parsers reject the document as not well-formed.
- Nessun caricamento
- Nessun limite di dimensione

Corrompi il tuo file XML
Calibrato per .xml, .xsd, .rss, .plist, e funziona altrettanto bene con qualsiasi altro formato.
Perché i file XML sono difficili da corrompere per bene
XML parsers are strict about well-formedness but tolerant about a great deal else. The reliable way to break an XML document is to attack the three things every parser checks first: the declaration, the encoding, and the balance of the tag tree.
Cosa distrugge questo strumento
- The XML declaration. The opening
<?xml version…?>processing instruction is destroyed, so encoding and version cannot be established. - Tag balance. Angle brackets and tag names are overwritten throughout, leaving elements permanently unclosed.
- Encoding validity. Invalid UTF-8 sequences make the document fail before the parser reaches the grammar.
- The root element. The closing bytes are destroyed, so the document root is never terminated.
Cosa vedrai dopo
| Applicazione | Comportamento |
|---|---|
| Browsers | "This page contains the following errors: not well-formed" with the offending line highlighted. |
Python ElementTree | Raises ParseError: not well-formed (invalid token). |
| Java / .NET parsers | Throw SAXParseException or XmlException on the first token. |
| XML editors | Refuse to load or open the file in plain-text mode with errors flagged. |
Motivi comuni per farlo
- Testing an XML ingestion endpoint against malformed input.
- Verifying that a SOAP or RSS consumer surfaces parse failures properly.
- Checking a configuration loader refuses a damaged file rather than starting with defaults.
- Producing not-well-formed fixtures for a conformance test suite.
Come corrompere un file XML
- Trascina il tuo file .xml nel riquadro qui sopra, oppure fai clic per sfogliare.
- Lascia il livello su Standard, a meno che tu non voglia un danno parziale (Light) o debba sconfiggere un software di recupero (Heavy).
- Premi Corrompi file. L'elaborazione avviene sul tuo dispositivo, quindi termina quasi subito.
- Scarica il risultato. Per impostazione predefinita mantiene il nome file e la lunghezza in byte originali.
Domande frequenti su XML
Does this break XML schema validation too?
It never gets that far. Schema validation happens after parsing, and the document fails well-formedness first.
Will it work on SVG, RSS or plist files?
Yes. All are XML underneath and use the same profile. There is also a dedicated SVG corrupter.
Can I keep it looking like valid XML?
Light level preserves most of the structure, so the file still looks like XML at a glance while failing to parse.
Is the file uploaded anywhere?
No. All processing happens in your browser and nothing is transmitted.
