Message

XML file is malformed

This error occurs when the compiler encounters a PLCopen XML file that is not valid XML. The file cannot be parsed because it violates XML syntax rules.

Example

This error typically occurs due to:

  1. Unclosed tags

  2. Mismatched tag names

  3. Invalid characters in the document

  4. Missing XML declaration

  5. Malformed attribute syntax

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://www.plcopen.org/xml/tc6_0201">
  <fileHeader companyName="Test" productName="Test"
  <!-- Missing closing > and rest of document -->

The XML parser will report this as malformed because the opening tag is incomplete.

To fix this error, ensure your XML file is well-formed:

  1. All tags must be properly closed

  2. Tag names must match exactly (case-sensitive)

  3. Attribute values must be quoted

  4. Special characters must be escaped (e.g., &lt; for <)

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://www.plcopen.org/xml/tc6_0201">
  <fileHeader companyName="Test" productName="Test" productVersion="1.0" creationDateTime="2024-01-01T00:00:00"/>
  <!-- Rest of valid XML document -->
</project>
