Find and increment at each occurence of string (loop)

I created script (sh shell) to generate vlc playlist based on some data files. All works fine so far except one string I do not know how to handle with.
Code:
VLCSTART='<vlc:id>'
VLCV=0
VLCEND='</vlc:id>'

Code:
echo -e $'\n'$'\t'$'\t'$'\t'$'\t'\$VLCSTART$VLCV$VLCEND

Output file contains several occurences of this:
Code:
        <track>
            <location>http://ts://</location>
            <title>name</title>
            <extension application="http://www.videolan.org/vlc/playlist/0">
                <vlc:id>0</vlc:id>
                <vlc:option>network-caching=1000</vlc:option>
            </extension>
        </track>

I need to create loop to increment each occurrence of '0' +1 in string '<vlc:id>0</vlc:id>' but the first occurrence has to stay '0'.

I am not good at loops, still learning.... Smilie

XmScrollBarSetValues(3X)												  XmScrollBarSetValues(3X)

NAME
XmScrollBarSetValues - A ScrollBar function that changes ScrollBar's increment values and the slider's size and position SYNOPSIS
#include <Xm/ScrollBar.h> void XmScrollBarSetValues (widget, value, slider_size, increment, page_increment, notify) Widget widget; int value; int slider_size; int increment; int page_increment; Boolean notify; DESCRIPTION
XmSetScrollBarValues changes the ScrollBar's increment values and the slider's size and position. The scroll region is overlaid with a slider bar that is adjusted in size and position using the main ScrollBar or set slider function attributes. Specifies the ScrollBar wid- get ID. Specifies the ScrollBar's slider position between XmNminimum and XmNmaximum. The resource name associated with this argument is XmNvalue. Specifies the size of the slider as a value between zero and the absolute value of XmNmaximum minus XmNminimum. The size of the slider varies, depending on how much of the slider scroll area it represents. This sets the XmNsliderSize resource associated with Scroll- Bar. Specifies the amount of button increment and decrement. If this argument is not zero, the ScrollBar widget automatically adjusts the slider when an increment or decrement action occurs. This sets the XmNincrement resource associated with ScrollBar. Specifies the amount of page increment and decrement. If this argument is not zero, the ScrollBar widget automatically adjusts the slider when an increment or decrement action occurs. This sets the XmNpageIncrement resource associated with ScrollBar. Specifies a Boolean value that when True, indicates a change in the ScrollBar value and also specifies that the ScrollBar widget automatically activates the XmNvalueChangedCallback with the recent change. If False, specifies any change that has occurred in the ScrollBar's value, but XmNvalueChangedCallback is not activated. For a complete definition of ScrollBar and its associated resources, see XmScrollBar(3X). SEE ALSO
