Пример 1. Saving a DOM tree into a file

<?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 'Wrote: ' . $doc->save("/tmp/test.xml") . ' bytes'; // Wrote: 72 bytes ?>

If you're working with an existing XML file that contains an entity definition with an external reference like this one:



[

  <!ENTITY % all.entities SYSTEM "all-entities.ent">

  %all.entities;

]>



Be warned that DOMDocument->save() will expand this to include all definitions in all referenced entities file(s) when it writes the file. In other words, the same section of your saved file would now look something like this:



<!ENTITY % all.entities SYSTEM "all-entities.ent">

<!--

  This file names all the entity files needed by .xml files in the

  current directory.  All ENTITY declarations should be given

  first, followed by references to the those entities.

--><!ENTITY % fixedchars.entities SYSTEM "../common/fixedchars.ent">

<!ENTITY % urls.entities SYSTEM "../refman-common/urls.ent">

<!ENTITY % phrases.entities SYSTEM "../common/phrases.ent">

<!ENTITY % ndb.entities SYSTEM "ndb.en.ent">

<!ENTITY minus "&#x2013;"><!-- 2013 is actually Unicode for ndash -->

<!ENTITY Oslash "&#216;">

<!ENTITY macr "&#175;">

<!ENTITY auml "&#228;">

[etc.]



I've not found a way to keep this from occurring.

The XML parser converts the text of an XML document into UTF-8, even if you have set the character encoding of the XML, for example as a second parameter of the DOMDocument constructor. After parsing the XML with the load() command all its texts have been converted to UTF-8.



In case you append text nodes with special characters (e. g. Umlaut) to your XML document you should therefore use utf8_encode() with your text to convert it into UTF-8 before you append the text to the document. Otherwise you will get an error message like "output conversion failed due to conv error" at the save() command. See example below:



<?php

// Text to insert into XML below

$txt = "a text with special characters like '

DOMDocument->save()
