And then the file ends.

I presume you mean the file gets truncated? In large files with some types of look-aheads there can be instances of this occuring, but I wouldn’t have thought this in your case.
Try this alternative regex.
Find What:(?-s)(.+?dateTimeHour.+\R<value>)\d+
Replace With:\1xx

Where xx is the number you wish to use, it can be any length i.e. 1, 3765 etc. In this case as we are capturing the previous line and a bit of the current line (so we only get the datetimehour values you want to change) we need to write it back, hence the \1 in front of the number you want to insert.

Hello Terry
Doesn’t quite work.

If I do that, the whole document gets replaced by the number I entered :(

The strange thing is that when I first started this thread, the help I was getting was always working! And the files are still XML, the structure is quite similar, although the properties are different. So I don’t get why neither the first tips I was provided nor the new ones are working.

For instance, there’s another thing I’d like to change:

This line appear multiple times along this large document, but with different values along the way.
If I wanted to replace al those different values with just one (like -10 for example), I can’t do that.

My regex works by capturing part of 1 line, then the first part of the next line. If the “whole” document is being replaced it suggests you don’t have many or most likely ANY CRLF (carriage return line feeds in it.

When the file is loaded in Notepad++ by default the left side shows line numbers. Can you determine if it only contains 1 or a small number of lines? If so then I would need to do some more testing, but my initially reaction would be to change that regex to:
Find What:(?-s)(.+?dateTimeHour.+\R?<value>)\d+
This will not force a CRLF between the 2 lines, but if it exists then it will include it.

Actually thinking further another amendment is needed so try
Find What:(?-s)(.+?dateTimeHour.+?\R?<value>)\d+
The .+? minimally tries to capture up to a possible CRLF sequence, and just beyond to the first (hopefully) sequence of the <value> tag.

Look mate,
I uploaded the file here: https://www83.zippyshare.com/v/rHBggLMf/file.html

Please look for lines like:

**<property name=“dateTimeHour” type=“uint32” container=“StaticArray” arraySize=“1”>

And/Or

**<property name=“gameMinExposure” type=“float” container=“StaticArray” arraySize=“1”>

Where the numbers between the <value> </value> tags can be different everytime you search for them.

And see if it works for you.

Thank you again.

Sadly my last regex was still not working. Getting to see the actual lines in the file has helped, having “indented” lines didn’t help.
So my latest version is
Find What:(?s-i)(gameMinExposure.+?)-*\d+(</value>)
Replace With:($1)123($2)

You would change the “gameMinExposure” to the correct tag name, such as the other one you were looking for “dateTimeHour”. Note I have added the -i to the modifier at the start of the line, the search string is case sensitive. So for example if your file had “Datetimehour” and this regex is looking for “dateTimeHour”, with the -i modifier it will NOT find it, this is by design. Remove the -i if you don’t care, then you can type the string in any format “DaTeTiMeHoUr” for example and it will find “datetimehour”, “DATETIMEHOUR” or any other combinations.

I also noted that the number to be replaced was sometimes negative. So my latest regex has to look for that possibility as well. If found, then it will be removed when writing the number back. So you type into the Replace With field the number you want (including a - at the front if desired) replacing the 123 there.

That’s amazing, Terry!
I will give it a try right now!

Thank you very much for all the help and quickness!

So… Terry!
I’m very sorry to keep dragging you into this, but a new issue came up.
It looks like when the value has a decimal, when I use the string you provided, it only replaces the part after the “.”.

For example:

If I want to replace “-12.5” with “11” at every found string, it actually comes up like this:

Using:
Find: (?s-i)(gameMinExposure.+?)-*\d+(</value>)
Replace With: ($1)11.5($2)

If I want to replace “-12.5” with “11” at every found string, it actually comes up like this:

OK, some more changes required then. The latest revision of the Find What regex is:
(?s-i)(gameMinExposure.+?<value>).+?(</value>)
So in this instance I’ve put the 2 tags (<value> and </value>) around the “other” characters (number) that we need to replace. So the .+? does not care what currently exists in this position, but whatever is there will be replaced with the new number which you have in the Replace With field.
