- How do I install shanethehat/pretty-xml in a Laravel application?
- Install it with Composer using composer require shanethehat/pretty-xml. The package is a plain PHP library without a Laravel service provider or facade, so you register your own binding in a service provider. Require ext-dom in your environment and confirm the package's composer.json constraints before pinning. Then inject the formatter rather than calling it statically.
- Does Pretty XML support Laravel 10, Laravel 11, and PHP 8?
- It has no Laravel-specific code, so framework compatibility is mostly a matter of PHP version and ext-dom. Check the package's composer.json for declared PHP constraints and whether a CI matrix proves them. Because it is not Laravel-aware, you own the integration glue and should test it on your target Laravel and PHP versions. The repository has limited public scrutiny, so verify the source and release metadata before adopting it.
- How do I pretty print an XML string in PHP with this package?
- Instantiate the formatter, pass the raw XML string or document, and receive indented output. The package wraps DOMDocument, so input must be well-formed XML and ext-dom must be available. In Laravel, resolve it from the container inside a service or adapter rather than using it in controllers. Confirm the exact method signature in the source because the public API is small and not framework-documented.
- How can I minify XML with Pretty XML, and is it safe?
- Minification removes insignificant whitespace, which is useful before logging or transmitting payloads. It is only safe when whitespace is truly insignificant in your schema. Stripping whitespace can destroy meaningful text nodes in mixed-content documents. Validate the minified output against your consumers and never minify signed or hash-verified XML.
- Is pretty-printing XML safe for mixed content or xml:space="preserve"?
- No, formatting is not semantically neutral in those cases. Pretty-printing inserts and normalizes whitespace, which changes text nodes in mixed content and can override documents that rely on xml:space="preserve". Only format XML where whitespace between elements is known to be insignificant. For mixed-content payloads, preserve the original bytes and skip formatting entirely.
- Does this package handle CDATA, comments, processing instructions, and namespaces correctly?
- It wraps DOMDocument, so behavior depends on how it serializes those constructs and on the underlying libxml version. Hand-rolled or wrapper formatters commonly diverge on CDATA, comments, processing instructions, DOCTYPE and entity declarations, namespace prefixes, and attribute quoting. Build a regression corpus covering each construct and compare output to DOMDocument's own serialization. Do not assume correctness without tests on your real documents.
- What happens if I pass malformed XML to Pretty XML?
- DOMDocument normally emits warnings and may return false or partial output for malformed XML, and the package may or may not convert that into an exception. Check the source for error handling before relying on it. Wrap calls defensively, validate input first, and fail closed in integration pipelines. Avoid silent passthrough because it can hide corrupt payloads.
- Why use Pretty XML instead of DOMDocument::formatOutput or XMLWriter?
- DOMDocument with formatOutput enabled and preserveWhiteSpace disabled covers many pretty-printing needs with no extra dependency. XMLWriter is a good fit for streaming generation and large documents. Pretty XML is only worth adding if it provides incremental convenience or behavior your baseline lacks. Define your own formatter interface so you can swap between the package and native implementations.
- Can pretty-printing or minifying break XML signatures, checksums, or caches?
- Yes, any byte-level change invalidates XML digital signatures, payload checksums, and caches keyed on content hashes. Formatting must never run before signing or after signature verification, and minification has the same problem in reverse. Keep the canonical bytes as the source of truth and apply formatting only at presentation or debug boundaries. Also avoid formatting on hot request paths.
- How should I test and mock an XML formatter in a Laravel application?
- Define your own formatter contract, bind an implementation in a service provider, and inject it so tests can substitute a fake. Write corpus tests with mixed content, CDATA, comments, namespaces, entities, and large documents, comparing output against expected bytes. Test malformed input behavior and confirm minification never strips significant whitespace. Feature-flag the package implementation so you can fall back to a native DOMDocument formatter.
