Description

This exact Buffer.toString() call prevents parsing XML files that are greater than 0x1fffffe8 characters:

I'm on Node.js v24.13.1, Apple Silicon macOS 26.3.

Input

The .dat file contained within the "RomVault" zip from this release: https://github.com/Eggmansworld/Datfiles/releases/tag/teknoparrot

Code

I don't believe it's consequential, but the options I'm using are:

new XMLParser({
    ignoreAttributes: false,
    ignoreDeclaration: true,
    ignorePiTags: true,
    parseTagValue: false,
    parseAttributeValue: false,
    attributeNamePrefix: '',
}).parse(buffer)

Output

The Buffer.toString() call throws with:

• code: ERR_STRING_TOO_LONG
• message: Cannot create a string longer than 0x1fffffe8 characters

expected data

My expectation is that the library can handle Buffers up to the size that the CPU architecture allows.
