How to Use the XML Encoder

Paste the raw string you want to encode into the input field.

The tool replaces <, >, &, ", and ' with their corresponding XML entity references.

Copy the encoded output and embed it safely inside an XML text node or attribute value.

What Is XML Encoding?

XML markup uses certain characters as structural delimiters — < and > define element tags, & begins entity references, and " and ' delimit attribute values. If these characters appear in your data, they must be replaced with entity references before being placed inside an XML document, or they'll be interpreted as markup rather than data, breaking the document's structure. XML encoding performs this substitution, converting raw strings into XML-safe text.

When to Use This Tool

Embedding user input in XML — Sanitize strings before inserting them into XML templates or documents to prevent malformed output.

Constructing XML payloads manually — When building XML request bodies by hand, encode any dynamic values that may contain reserved characters.

Preventing XML injection — Encoding untrusted input before inserting it into XML structures is a basic defense against XML injection attacks.

Preparing content for XML feeds — Encode article content, descriptions, or titles before including them in RSS or Atom feed elements.

FAQ

Answers about this tool and how your data is handled.

Which characters are encoded?

The five XML reserved characters: & → &amp;, < → &lt;, > → &gt;, " → &quot;, ' → &apos;.

Should I encode attribute values differently from text nodes?

The same five characters apply in both contexts. In attribute values, quote characters (" and ') are particularly important to encode if they match the delimiter used.

Is XML encoding the same as XML escaping?

Yes — the terms are used interchangeably. See also the XML escape tool, which performs the same operation.

Does this tool send my data to a server?

No. Encoding runs entirely in your browser. Nothing is uploaded.

Will this protect against all XML injection vectors?

Encoding reserved characters is the primary defense for text content and attribute values. For full XML injection prevention in production systems, encoding should be combined with schema validation and strict input handling at the application level.
