DOMDocument:saveXML 返回值替空字符串
DOMDocument::saveXML 返回值为空字符串
PHP手册中的的实例：
$doc = new DOMDocument('1.0');
// we want a nice output
$doc->formatOutput = true;
$root = $doc->createElement('book');
$root = $doc->appendChild($root);
$title = $doc->createElement('title');
$title = $root->appendChild($title);
$text = $doc->createTextNode('This is the title');
$text = $title->appendChild($text);
echo "Saving all the document:n";
$xmlContent = $doc->saveXML();
var_dump($xmlContent);
打印出的结果是：
Saving all the document: string(72) " "
为什么没有打印出完整的XML？请各位前辈指点，Thanks!
PHP
saveXML
------解决方案--------------------
请在文本方式下查看
Saving all the document:DOMDocument:saveXML 返回值替空字符串
string(72) "
This is the title
"
