If I'm not mistaken, in XML these are considered to be exactly the same thing and any parser should recognise both forms. But still, I think you should be able to change this behaviour by passing the LIBXML_NOEMPTYTAG
constant to your DOMdocument's saveXML()

@thijskh Thank you very much for your help, the following is my method, left to the people.
protected function generateXMLSignFields($xml, $prefix = 'ds')
{
// 加载要签名的XML
$doc = new \DOMDocument();
$doc->loadXML($xml);
// 创建一个新的安全对象
$objDSig = new XMLSecurityDSig($prefix);
// 使用c14n专属规范化
$objDSig->setCanonicalMethod(XMLSecurityDSig::C14N);
// 签名使用 SHA-256
$objDSig->addReference(
$doc,
XMLSecurityDSig::SHA1,
['http://www.w3.org/2000/09/xmldsig#enveloped-signature'],
['force_uri' => true]
);
// 创建一个新的(私有)安全密钥
$objKey = new XMLSecurityKey(XMLSecurityKey::RSA_SHA256, ['type' => 'private']);
// 如果密钥有密码,则使用它进行设置
// $objKey->passphrase = '<passphrase>';
// 加载私钥
$objKey->loadKey("-----BEGIN RSA PRIVATE KEY-----\n" . wordwrap($this->privateKey, 64, "\n", true) . "\n-----END RSA PRIVATE KEY-----\n");
// 对XML文件签名
$objDSig->sign($objKey);
// 将关联的公钥添加到签名
// $objDSig->add509Cert("-----BEGIN PUBLIC KEY-----\n" . wordwrap($this->publicKey, 64, "\n", true) . "\n-----END PUBLIC KEY-----\n");
// 将签名附加到XML
$objDSig->appendSignature($doc->documentElement);
// saveXML 里面 LIBXML_NOEMPTYTAG 是为了不简写空值的标签。例:(<test /> => <test></test>)
return $doc->saveXML($doc->documentElement, LIBXML_NOEMPTYTAG);
}
Closing as appears everything is all set
How to display two tags when the node content is empty.
For example, in this case:
<CanonicalizationMethod Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315" /> <SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256" />
That's what I want
