Because SimpleXML transforms the values & to & whe reading from file or string, the values becomes invalid for use when adding childs later on. This simple conversion to the example above fixes this problem.
class XMLElement extends SimpleXMLElement
{
public function addElement (SimpleXMLElement $xmlTree,$root=false)
{
if($root)
{
$child = $this->addChild ($xmlTree->getName());
foreach ($xmlTree->attributes() as $k => $v)
{
$child->addAttribute($k,$v);
}
$child->addElement($xmlTree);
}
else
{
foreach ($xmlTree as $childName => $childTree)
{
$child = $this->addChild($childName,$this->fix_content((string) $childTree)); // this is not comletely correct
foreach ($childTree->attributes() as $k => $v)
{
$child->addAttribute($k,$v);
}
$child->addElement($childTree->children());
}
}
}
#When the xml is read by simplexml_load_file or simplexml_load_file the values that contains & is converted to &. And then it is not possible to add these values without getting errors.
#THis function should fix this
public function fix_content($value) {
return str_replace('&', '&', $value);
}
}
SimpleXMLElement->addAttribute()
