XML Encoder

Encode special characters for safe use in XML.

What is XML Encoder?

The XML Encoder converts raw text containing special characters into properly escaped XML entities, ensuring your strings are safe to embed in any XML document. Characters like <, >, &, ", and ' carry special meaning in XML syntax — leaving them unescaped will break parsing, corrupt data, or introduce security vulnerabilities. This tool handles all necessary transformations automatically, producing standards-compliant output every time.

For developers working with XML-based APIs, configuration files, data feeds, or serialization formats, manually escaping content is tedious and error-prone. A single unescaped ampersand in a product description or a stray angle bracket in user-generated content can invalidate an entire XML document. This tool eliminates that risk by providing instant, reliable encoding — making it an essential part of any XML workflow.

How to Use

Using the tool is straightforward: paste or type your raw text into the input field and the encoded XML output is generated instantly. For example, the string <script>alert('Hello & World')</script> becomes &lt;script&gt;alert(&apos;Hello &amp; World&apos;)&lt;/script&gt;. Every reserved XML character is mapped to its corresponding named or numeric entity, and the result is ready to be safely inserted into an XML element or attribute value.

The encoder handles all five predefined XML entities: &amp; for &, &lt; for <, &gt; for >, &quot; for ", and &apos; for '. These cover the full set of characters that can break well-formed XML under any compliant parser. Unicode characters and multi-line content are also supported without issue.

One important edge case to be aware of: this tool encodes the content intended to go inside XML tags — it does not generate or modify the surrounding XML structure itself. If you are building complete XML documents programmatically, you should encode individual field values before inserting them, rather than encoding an entire XML string, which would double-encode already valid markup.

Use Cases

API Payloads: When constructing XML request bodies for SOAP services or REST APIs that return XML, encode user-supplied or database-retrieved values before interpolating them into your XML template to prevent malformed requests.
Data Feeds: Product descriptions, article summaries, and user bios pulled from a CMS often contain ampersands, quotes, and angle brackets — encode them before writing to RSS, Atom, or sitemap XML feeds to ensure feed validators pass without errors.
Configuration Files: Application config in XML format (like Maven's pom.xml or Android's AndroidManifest.xml) sometimes requires dynamic values containing special characters; encoding those values prevents build or runtime parsing failures.
Security Hardening: When reflecting user input into XML-based responses or storing it in XML databases, encoding all special characters is a critical mitigation against XML injection attacks, where malicious input could otherwise alter document structure or expose sensitive data.
