2. php code

The code is as follows:

$ Dom = new DOMDocument ('1. 0 ');
$ Dom-> load ('x. XML ');
$ Em = $ dom-> getElementsByTagName ('Emotions ');
$ Em = $ em-> item (0 );
$ Items = $ em-> getElementsByTagName ('ITEM ');
Foreach ($ items as $ ){
Foreach ($ a-> attributes as $ B ){
If ($ B-> nodeValue = 'birthday '){
$ A-> setAttribute ('name', 'nbirthday ');
}
}
}
$ T = $ dom-> createElement ('ITEM ');
$ T-> setAttribute ('name', 'x ');
$ T-> setAttribute ('src', 'www .baidu.com ');
$ T-> setAttribute ('duration', 'duration ');
$ Em-> appendChild ($ t );
$ Dom-> save ('x. XML ');
?>

PHP parses XML document attributes and edits

The code is as follows:

// Read xml
$ Dom = new DOMDocument ('1. 0 ');
$ Dom-> load ('data. XML ');
$ Em = $ dom-> getElementsByTagName ('videoos '); // outermost node
$ Em = $ em-> item (0 );
$ Items = $ em-> getElementsByTagName ('video'); // Node
// Remove the following section if you do not need to read it.
Foreach ($ items as $ ){
Foreach ($ a-> attributes as $ B) {// $ B-> nodeValue; node attribute value $ B-> nodeName; node attribute name
Echo $ B-> nodeName;
Echo ":";
Echo $ B-> nodeValue;
Echo"
";
}
}
// Below is a new line written to xml
$ T = $ dom-> createElement ('video ');// $ T-> setAttribute ('title', '1 ');// $ T-> setAttribute ('src', '2 ');// $ T-> setAttribute ('IMG ', '1 ');// $ Em-> appendChild ($ t );//
$ Dom-> save ('data. XML ');
?>

The xml document at that time:

The code is as follows:

// The following file is modified later. you can modify the xml file.

The code is as follows:

$ Doc = new DOMDocument ();
$ Doc-> load ('data. XML ');

// Find the videos node
$ Root = $ doc-> getElementsByTagName ('videoos ');

// The first videos node
$ Root = $ root-> item (0 );

// Find the video node under the videos node
$ Userid = $ root-> getElementsByTagName ('video ');

// Traverse all video nodes
Foreach ($ userid as $ rootdata)
{
// Traverse all attributes of each video node
Foreach ($ rootdata-> attributes as $ attrib)
{
$ AttribName = $ attrib-> nodeName; // nodeName is the attribute name.
$ AttribValue = $ attrib-> nodeValue; // nodeValue indicates the attribute content.

// Search for the node content whose property name is ip
If ($ attribName = 'IMG ')
{
// Find the node content whose property content is ip
If ($ attribValue = '1 ')
{
// Change the property to img and the content of img to 1 to image;
$ Rootdata-> setAttribute ('IMG ', 'image ');
$ Doc-> save ('data. XML ');
}
}
}
}
?>
