domxml_xmltree
(PHP 4 >= 4.2.0)
domxml_xmltree — Создает дерево объектов PHP из XML документа
Описание
Функция разбирает XML документ из строки str и возвращает соответствующее дерево объектов PHP.
Эта функция изолирована от остальных, это означает, что невозможно получить доступ к дереву, используя другие функции. Изменение дерева, например добавление к нему узлов, не имеет смысла, потому как на данный момент нет способа получить из этого дерева обратно XML файл.
Тем не менее, эта функция может оказаться полезной, если требуется только прочитать файл и исследовать содержимое.
Список параметров
- str
-
Содержимое XML файла.
Возвращаемые значения
Возвращает дерево DOM объектов, начиная с DomDocument.

This is a genuinely useful function, however, as with any DOM-based markup parser, be mindful of the size of the XML document you are parsing. Representing very large XML files as object structures requires *a lot* of memory and processing, and may even crash your server (which is what happened to my Apache when I tried parsing a 2MB XML file using this function, just for fun... ;).Replacing line 10 works well, but replacing line 15 causes some errors. I have a tree like:
<admin>
<user level="0">
<username>admin</username>
<password>admin_pass</password>
</user>
<user level="1">
<username>moder</username>
<password>moder_pass</password>
</user>
</admin>
when I remove those brackets only the last <user> is included into array. In this example it would be
<user level="1">
<username>moder</username>
<password>juozux</password>
</user>
no user name admin, etc.
p.s. I don't store passwords in plain text in xml, that was just an example :))
You can modify the returned DomDocument, and dump it as an XML fileby using DomDocument->dump_mem() or DomDocument->dump_file().
