How to fix an XML declaration that is not at the start

The preloaded document puts <?xml version="1.0"?> after the root element. The XML declaration describes the document itself and, when used, must appear before the document element rather than as trailing processing content. This tool is free to use. No account or payment is required.

Steps

  1. Search the document for <?xml and confirm how many declarations are present.
  2. Move the single required declaration to the beginning of the XML source.
  3. Remove declarations copied from embedded fragments and validate the final combined document.

The XML declaration belongs to the document prolog

It can specify version and encoding information for the XML document, but it is not an ordinary processing instruction that can be inserted after the root element.

Concatenating complete XML files often creates this error

If multiple source files each include their own declaration, joining their raw text can leave later declarations in the middle of the combined document. Merge the data at the XML tree level instead of concatenating full files.

Misplaced XML declaration example

Move the XML declaration before the document element.

Invalid XML

<root/><?xml version="1.0"?>

Corrected XML

<?xml version="1.0"?><root/>
