如何在cakePHP1.3中编辑XML值？

Question

I have XML resource which provide this:

<container>
    <element id="first-el">
        <name>My element</name>
        <size>20</size>
    </element>
    <element>
        <name>Your element</name>
        <size>30</size>
    </element>
</container>

What i want to do is to change value of <size> , where id is "first-el" , and change 20 to 50.

The resulting XML should look like this:

<container>
    <element id="first-el">
        <name>My element</name>
        <size>50</size>
    </element>
    <element>
        <name>Your element</name>
        <size>30</size>
    </element>
 </container>

I tried to use addChild() of XML Method in CakePHP, but is there a better way to do this?

Answer 1

I have no idea what sort of additional functionality CakePHP provides in regards to XML, but there already tools for this in plain old PHP:

• DOM Document
• Simple XML

Both let you manipulate existing XML data.

There is a class in CakePHP that will handle all of this for you. You can read the specifics here:

CakePHP 1.3: http://book.cakephp.org/1.3/en/view/1485/Xml

CakePHP 2.0: http://book.cakephp.org/2.0/en/core-utility-libraries/xml.html
