DOMDocument->saveXML() — Dumps the internal XML tree back into a string

options: Additional Options. Currently only LIBXML_NOEMPTYTAG is supported.

返回值

Returns the XML, or FALSE if an error occurred.

错误／异常

DOM_WRONG_DOCUMENT_ERR: Raised if node is from another document.

更新日志

范例

Example#1 Saving a DOM tree into a string

  <?php 
 
$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"  ; 
echo   $doc  ->  saveXML  () .   "\n"  ; 
 
echo   "Saving only the title part:\n"  ; 
echo   $doc  ->  saveXML  (  $title  ); 
 
  ?>

上例将输出：

Saving all the document:
<?xml version="1.0"?>
<book>
  <title>This is the title</title>
</book>

Saving only the title part:
<title>This is the title</title>
