VQMod offset issue in OpenCart

Question

I`m trying to replace a chunk of code on the model with custom code, that I wrote.

Here is the code. I works, but it leaves a lot of offset. Maybe there is a better way to do this

<operation info="Example of the vQmod">
<search position="replace" offset="3"><![CDATA[
Some code I want to Replace
Some code I want to Replace
Some code I want to Replace
]]></search>
<add><![CDATA[
Replaced Code
Replaced Code
Replaced Code
]]></add>
</operation>

Vqmods offset value is for replacing a line and the following x lines, however the search is for one line only. Vqmod doesn't match multiple lines. — HDP, Sep 23 '15 at 08:46

Vqmods offset value is for replacing a line and the following x lines, however the search is for one line only. Vqmod doesn't match multiple lines in search.

Example :

Input

 public function index() {
        $a = rand();
        $b = rand();
        if ($a == $b) {
            echo 'oh noes';
            return false;
        }
    }

Script

 <?xml version="1.0" encoding="UTF-8"?>
    <modification>
        <id>Replace many lines with one</id>
        <version>1.0</version>
        <vqmver>2.X</vqmver>
        <author>xxx</author>
        <file name="path/to/testfile.php">
            <operation info="Replace index function">
                <search position="replace" offset="7"><![CDATA[
                public function index() {
                ]]></search>
                <add><![CDATA[
                public function index($arr = array()) {
                    foreach ($arr as $a) {
                        echo $a;
                        }
                }
                ]]></add>
            </operation>
        </file>
    </modification>

Output

 public function index($arr = array()) {
        foreach ($arr as $a) {
            echo $a;
            }
    }

Note : There are still 7 blank lines. The offset clears the extra 7 lines of code from the input, but the replaced code is added in place of the initial line. So there will be 7 extra spaces after the new code, but it will not affect the code functionality, only the look of the vqcache file which is of no importance.

In Opencart, you cannot search for multiple lines of code and replace it with new multiple lines of codes. It can only search a single line and then replace or add with single line or multiple lines of code.

Offset is to search a single line of code and then offset the number of lines below and then replace or add new coding. Something like this:

   <operation info="Example of the vQmod">
    <search position="replace" offset="3"><![CDATA[
    code I want to Replace at offset line 3
    ]]></search>
    <add><![CDATA[
    Replaced Code
    add code
    add code
    ]]></add>
    </operation>
