How to Fix XML Errors - Step by Step Guide

Step 1

Input Your Broken XML

Got broken XML that's causing parse errors? Let's fix it! After fixing, use our XML validator, formatter, or learn about XML. Paste your problematic XML data:

•

Paste broken XML: Copy error-prone XML from your config files, API responses, or data exports

•

Fix common errors: Automatically repairs tag errors, attribute issues, quote problems, and other syntax errors

•

Try sample XML: Click "Sample" to load broken XML and see the tool in action

Note: For very large XML files, the server may not be able to handle the processing. Please use smaller XML chunks for best results.

Example: Common XML Errors

Here are typical XML syntax errors that break parsing:

<?xml version="1.0" encoding="UTF-8"?>
<person>
  <name>Sarah Chen
  <email>[email protected]</email>
  <age>28</age>
  <skills>
    <skill>JavaScript</skill>
    <skill>Python
    <skill>React</skill>
  </skills>
  <active>true<active>
  <projects>
    <current>Website Redesign</current>
    <completed>Mobile App
  </projects>
</person>
Step 2

Review Error Detection

The tool automatically scans your XML and identifies all syntax errors with precise locations and descriptions:

•

Error highlighting: See exactly where each syntax error occurs in your XML

•

Detailed descriptions: Get clear explanations of what's wrong and why it breaks parsing

•

Line numbers: Pinpoint exact locations of errors for easy identification

Most Common XML Errors and How to Fix Them

1. Missing Closing Tags

XML requires all tags to be properly closed.

❌ Wrong:

<name>Sarah

✅ Correct:

<name>Sarah</name>
2. Mismatched Tags

Opening and closing tags must match exactly.

❌ Wrong:

<active>true<Active>

✅ Correct:

<active>true</active>
3. Unquoted Attributes

All attribute values must be enclosed in quotes.

❌ Wrong:

<item id=123>

✅ Correct:

<item id="123">
4. Special Characters Not Escaped

Special characters must be escaped in XML.

❌ Wrong:

<text>A & B</text>

✅ Correct:

<text>A &amp; B</text>
Step 3

Apply Fixes and Validate

Use the auto-fix feature to correct errors, then validate your fixed XML:

•

Auto-fix: Automatically correct common errors like missing tags and attribute quotes

•

Validation: Confirm your XML is now valid and ready to use

Best Practices for Working with XML

•

Always Validate Before Deployment:

Run your XML through a validator before using it in production to catch syntax errors early.

•

Use an XML Linter in Your IDE:

Modern code editors like VS Code have built-in XML validation that highlights errors as you type.

•

Keep XML Simple and Readable:

Use proper indentation and formatting to make your XML easy to read and maintain.

•

Test with Different Parsers:

Different systems may have slightly different XML parsing requirements. Test across platforms.
