Description
I am using Saxon-HE 11.4 to serialize a XHTML document.
The document already defines the meta element :
<meta charset="utf-8"/>
Using the xml transformer, the MetaTagAdjuster now adds an additional meta element:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
Having these two charset declarations in the XHTML document is illegal.
We can avoid inserting the content type at all with this setting:
transformer.setOutputProperty(SaxonOutputKeys.INCLUDE_CONTENT_TYPE, "no")
However, I think the MetaTagAdjuster should check if the charset is already defined.
Example: When having the following
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
</head>
</html>
in a Document object and transforming it to written XHTML. It results in
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta charset="utf-8" />
</head>
</html>
