I am trying to replace a period with a colon within a time stamp but without effecting other periods in in the text.
<trkpt lat="31.579166667" lon="120.295263333">
<ele>24.533331553</ele>
<time>2007-05-05T11:20:57.927Z</time>
</trkpt>
In the <time> row I need to change the last . to : this has always the Z character 3 places after
It should look like
<trkpt lat="31.579166667" lon="120.295263333">
<ele>24.533331553</ele>
<time>2007-05-05T11:20:57:927Z</time>
</trkpt>
