我使用以下方法在
PHP中导出了一个xml文件：
$xmldoc = new DOMDocument();
$xmldoc->formatOutput = true;
$xmldoc->encoding="Shift_JIS";
// create root nodes
$root = $xmldoc->createElement("TableData");
$xmldoc->appendChild( $root );
$xmldoc->save($filename);
结果：
<?xml version="1.0" encoding="Shift_JIS"?> <TableData> </TableData>
现在,我想添加行<！DOCTYPE TableDef SYSTEM“TableData.dtd”>喜欢：
<?xml version="1.0" encoding="Shift_JIS"?>
<!DOCTYPE TableDef SYSTEM "TableData.dtd">
<TableData> </TableData>
如何在导出的xml中添加DOCTYPE？谢谢.
见
PHP DOM: change doctype of existing DOMDocument
原文链接：https://www.f2er.com/php/444946.htmlWhen creating a DOMDocument with 07001,you can specify a doctype as the third argument in the constructor. This doctype then gets “tied” to the document and you can retrieve it later with $document->doctype.
