XML解析报错Msg 9442：编码名称语法错误求解

Hey there, let's tackle this XML parsing error you're hitting—Msg 9442 is almost always tied to a problem with the encoding declaration in your XML file's first line. Here's how to fix it step by step:

Why This Happens #

The error message points to "incorrect encoding name syntax" at line 1, character 38. That means somewhere in your XML's opening declaration (the <?xml ... ?> line), the encoding attribute has a syntax issue—like a misspelling, invalid characters, or a format that doesn't follow XML standards.

Step 1: Inspect Your XML File's First Line #

Grab a text editor that shows character positions (Notepad++ works great for this) and open E:\Scripts\apc.xml. Jump to line 1 and find the 38th character—this is where the invalid syntax lives.

Common mistakes to look for:

• Misspelled encoding names (e.g., UTF8 instead of UTF-8, iso88591 instead of ISO-8859-1)
• Extra spaces or invalid characters in the encoding value (e.g., encoding="UTF 8" with a space, or encoding="UTF_8" with an underscore)
• Typos in the attribute itself (e.g., encodng instead of encoding)

Step 2: Fix the Encoding Declaration #

Replace the problematic encoding line with a valid, standard declaration. Examples of correct syntax:

<?xml version="1.0" encoding="UTF-8"?>

or

<?xml version="1.0" encoding="ISO-8859-1"?>

If you're unsure of the file's actual encoding, you can even remove the encoding attribute entirely—SQL Server will auto-detect the file's encoding:

<?xml version="1.0"?>

Step 3: Re-Run Your SQL Code #

Once you've fixed the XML file, execute your original SQL script again:

declare @filedata xml 
select @filedata = BulkColumn from openrowset(bulk 'E:\Scripts\apc.xml',single_blob) x;

This should resolve the parsing error, as SQL Server will now recognize a valid encoding name (or auto-detect the encoding correctly).
