modify xml file php script

how to create script that modify xml file

sample xml file:

<root>
<parent name="a" id="1">
<child name="a.a" id="1.1" />
<child name="a.b" id="1.2" />
<child name="a.c" id="1.3" />
</parent>
<parent name="b" id="2">
<child name="b.a" id="2.1" />
</parent>
<parent name="c" id="3">
<child name="c.a" id="3.1" />
<child name="c.b" id="3.2" />
</parent>
</root>

php script should be able to modify the xml file. it should be able to
insert a parent element say between parent A and parent B. the id of
the new parent element should be parent B with its child respectively.
the parent elements below the new element should adjust the ids. in the
example above, parent B id should be 3 and its child id should be 3.1.
same goes to parent C and its childs.
result would be:
<root>
<parent name="a" id="1">
<child name="a.a" id="1.1" />
<child name="a.b" id="1.2" />
<child name="a.c" id="1.3" />
</parent>
<parent name="newparent " id="2">
<child name="newparent .a" id="2.1" />
<child name="newparent .b" id="2.2" />
</parent>
<parent name="b" id="3">
<child name="b.a" id="3.1" />
</parent>
<parent name="c" id="4">
<child name="c.a" id="4.1" />
<child name="c.b" id="4.2" />
</parent>
</root>

Hi,

DOM should be your friend, for Documentation read this:

Have fun ..

Re: modify xml file php script

actually, im more concern about the logic behind of the script. how do
you make the id update in cascading manner. anyway, thanks for the reply

Re: modify xml file php script

Hm ..

this maybe an answer but there could be better solutions that my one :-)

<?php

// ... fetch your id with DOM

$id_array = explode(".", $id);

// id[0] == first number of ID
// id[1] == second number of ID
// count up second one

id[1]++;

// connect id that you have back x.x

$id = implode(".",$id[0].$id[1]);

// write id back to XML (using DOM) ...

?>
