To match the string starting with <garbage and ending with the closest matching > after that, try matching using the single BRE or ERE <garbage[^>]*>.
Woot! So easy to do having been told this! Thank you! Smilie

Code:
#include <string>
#include <iostream>
#include <regex>
using namespace std;

int main(int argc, char * argv[]) {

	string test;

	test="This html code <text blah >contains <garbage blah blah >. All tags must go, <text > but some must be replaced with <garbage blah blah > without easing other info.";

	regex reg("<garbage[^>]*>");
	test = regex_replace(test, reg, "important info");

	cout << test << endl;

	return 0;
}

Result:
Code:
This html code <text blah >contains important info. All tags must go, <text > but some must be replaced with important info without easing other info.

Something tells me this regex function is going to be a livesaver! Smilie

Okay, now to do what I do best...

... sleep. Smilie

NAME

       tracker-tag - Add, remove and list tags.

SYNOPSIS

       tracker-tag [OPTION...] FILE [FILE...]

DESCRIPTION

       tracker-tag allows the caller add tags, remove tags and list tags by URN or to list all tags and the files associated with them.

       The FILE argument can be either a local path or a URI. It also does not have to be an absolute path.

OPTIONS

       -?, --help
	      Show summary of options.

       -l, --limit=N
	      Limit search to N results. The default is 512.

       -o, --offset=N
	      Offset the search results by N. For example, start at item number 10 in the results. The default is 0.

       -r, --or-operator
	      Use OR for search terms instead of AND (the default)

       -t, --list
	      List  all tags. Results include the number of files associated with that tag and the tag's unique identifier. You can show the files
	      associated with each tag by using --show-files.

       -s, --show-files
	      Show the files associated with each tag. This option is ONLY available WITH the --list option.

       -a, --add=TAG
	      Add a tag with the name TAG.  If no FILE arguments are specified, the tag is simply created (if it  didn't  already  exist)  and	no
	      files are associated with it. Multiple FILE arguments can be specified.

       -d, --delete=TAG
	      Delete  a tag with the name TAG.	If no FILE arguments are specified, the tag is deleted for ALL files. If FILE arguments are speci-
	      fied, only those files have the TAG deleted.

       -V, --version
	      Print version.
