Sane DOMParser Errors

sane-domparser-error is a JavaScript utility library designed to standardize error handling for DOMParser and XMLHttpRequest (when `responseType = 'document'`) in web environments. Typically, when an XML document cannot be parsed, these native APIs do not throw an exception but instead return a document containing a `<parsererror>` element. This library abstracts away the inconsistencies of the `<parsererror>` document across different browsers, providing a consistent mechanism to detect and report parsing failures as standard JavaScript `Error` objects. The package is currently at version 0.2.0, with its last update over a decade ago, indicating a maintenance status with a very infrequent release cadence. Its primary differentiator is simplifying robust XML parsing error detection, which is complex due to browser-specific `parsererror` document structures and namespaces.
