HTML to XML Converter
Convert HTML markup into well-formed XML using the browser's native DOMParser and XMLSerializer, which handles tag closing, entity encoding, and namespace cleanup automatically. Toggle pretty-print to add readable indentation, or keep it compact for programmatic use. Paste your HTML and the XML output appears instantly — no files are uploaded anywhere.

What is HTML to XML Converter?
HTML and XML share angle-bracket syntax but differ critically in strictness: HTML allows unclosed tags, unquoted attributes, and void elements without self-closing syntax. XML requires none of that. When an XML pipeline, EPUB generator, XSLT processor, or XML content management system receives HTML, it typically fails or silently corrupts the structure. This tool converts HTML to well-formed XHTML by correcting everything the XML parser would reject: void elements (<br>, <img>, <input>) become self-closing (<br/>, <img/>, <input/>), all attributes are double-quoted, unclosed tags are closed, and special characters in text content are entity-encoded. Named HTML entities not defined in XML ( , —) are converted to numeric character references ( , —). The output is valid XML that passes an XML parser without modification, with an optional xmlns="http://www.w3.org/1999/xhtml" declaration for XHTML compatibility.
How to Use
- 1
Paste Your HTML
Paste an HTML snippet or full document into the input editor. The tool uses an HTML parser (not an XML parser) to handle non-strict HTML5, then serialises the DOM as well-formed XML.
- 2
Configure XML Output
Choose whether to add the XML declaration (<?xml version="1.0"?>), set the output character encoding, and select whether to use XHTML namespace (xmlns="http://www.w3.org/1999/xhtml").
- 3
Convert to XML
Click "Convert to XML". Self-closing void elements (<br>, <img>, <input>) become self-closing XML tags (<br/>, <img/>); all attributes are properly double-quoted; unclosed tags are closed.
- 4
Copy or Download the XML
Copy the XML for use in an XSLT pipeline, EPUB generator, or XML content management system — or download it as a .xml file.
Common Use Cases
HTML to XHTML Migration
Convert HTML documents into well-formed XML (XHTML) for use in XML-based publishing pipelines, EPUB generation, or XML content management systems that require valid XML input.
Web Scraping Data Structuring
Convert scraped HTML content into XML for processing with XPath queries, XSLT transformations, or XML-native tools that provide more powerful querying than HTML parsers.
Content Pipeline Preprocessing
Transform HTML content from web editors, email templates, or CMS exports into XML as a preprocessing step for content transformation pipelines using XSLT stylesheets.
RSS Feed Item Content
Convert HTML article content into XML-safe markup for embedding in RSS feed <content:encoded> or <description> elements, ensuring feed validity and compatibility with feed readers.
Conversion Examples
HTML → Well-Formed XML
Self-closing tags, quoted attributes, and proper nesting make the output valid XML.
Input JSON
<div class="card"> <h2>Alice Smith</h2> <p class="role">Senior Engineer</p> <img src="alice.jpg" alt="Alice"> </div>
Output CSV
<?xml version="1.0" encoding="UTF-8"?> <div class="card"> <h2>Alice Smith</h2> <p class="role">Senior Engineer</p> <img src="alice.jpg" alt="Alice" /> </div>
HTML Table → XML Data Structure
An HTML table is converted to a semantic XML representation.
Input JSON
<table> <tr><th>Name</th><th>Role</th></tr> <tr><td>Alice</td><td>Engineer</td></tr> </table>
Output CSV
<table>
<thead>
<tr><th>Name</th><th>Role</th></tr>
</thead>
<tbody>
<tr><td>Alice</td><td>Engineer</td></tr>
</tbody>
</table>
