DOMCharacterData Function insertData

PHP Version: (No version information might be only in CVS. I have used this function in PHP5)

DOM: W3C DOM Level 1

Description

This function inserts a string at a specified position in a Text Node (DOMCharacterData).

Usage:

voidDOMCharacterData->insertData ( int offset, string data)

Inserts string data at position offset.

Throws DOMException if offset is negative or greater than the number of 16-bit units in data.

Example:

The XML file, which I have used contains following data. I have stored this file in “c:/topxml_demo/php/xml_files/employee.xml” directory.

<?xml version="1.0" encoding="UTF-8"?>

<employee>

            <employeename>test</employeename>

            <employeeaddress>test123</employeeaddress>

            <SSN>12343456</SSN>

            <company>TOPXML</company>

</employee>

PHP Code:

<?php

    $doc = new DomDocument;

// Load the xml file into DOMDocument

$doc->Load('C:/topxml_demo/php/xml_files/employee.xml');

// We retrieve the attribute named id of the employee element

$employee = $doc->getElementsByTagName('employee')->item(0);

//Create a new Element

$newElement = $doc ->createElement('surname');

//create a Text Node

$textNode = $doc ->createTextNode ("Text Node Created");

//insert some text in 5th postion of Text Node. Here I have inserted “'Inserted at 5th position” at 5^thpostion so the new text node should be “Text Inserted at 5th position Node Created”

$textNode->insertData(5,'Inserted at 5th position ');

//append the Text Node into the newly created node

$newElement -> appendChild($textNode);

//append the new element to the employee element

$employee  -> appendChild($newElement);

//save the DOMDocument into a file

$test = $doc->save("C:/topxml_demo/php/xml_files/save1.xml");

 echo "<B>DOMCharacterData->insertData example<B>"

 ?>

Output:

The Content of save1.xml is

<?xml version="1.0" encoding="UTF-8"?>

<employee>

     <employeename>test</employeename>

     <employeeaddress>test123</employeeaddress>

     <SSN>12343456</SSN>

     <company>TOPXML</company>

     <surname>Text Inserted at 5th position Node Created</surname>

</employee>
