but the frequency of that data is not fixed, so sometimes it may have 4 lines, or 6 lines or whatever in that file. However, the last line will always have empty space/line below it. (13 Replies)

Hi !
I try to change a time-stamp hh:mm:ss allways to full ten-minutes.
example: 12:51:03 to 12:50:03
sed 's/::/:{0-5}0:/g' file.txt
but it will not work propperly, because the minute-decade will be replaced with the bracket-term {0-5}. Can someone please give me a hint?
Thanks in... (6 Replies)

NAME
xmlif - conditional processing instructions for XML
SYNOPSIS
xmlif [attrib=value...]
DESCRIPTION
xmlif filters XML according to conditionalizing markup. This can be useful for formatting one of several versions of an XML document
depending on conditions passed to the command.
Attribute/value pairs from the command line are matched against the attributes associated with certain processing instructions in the docu-
ment. The instructions are <?if> and its inverse <?if not>, <?elif> and its inverse <?elif not>, <?else>, and <?fi>.
Argument/value pairs given on the command line are checked against the value of corresponding attributes in the conditional processing
instructions. An `attribute match' happens if an attribute occurs in both the command-line arguments and the tag, and the values match. An
`attribute mismatch' happens if an attribute occurs in both the command-line arguments and the tag, but the values do not match.
Spans between <?if> or <?elif> and the next conditional processing instruction at the same nesting level are passed through unaltered if
there is at least one attribute match and no attribute mismatch; spans between <?if not> and <?elif not> and the next conditional process-
ing instruction are passed otherwise. Spans between <?else> and the next conditional-processing tag are passed through only if no previous
span at the same level has been passed through. <?if> and <?fi> (and their `not' variants) change the current nesting level; <?else> and
<?elif> do not.
All these processing instructions will be removed from the output produced. Aside from the conditionalization, all other input is passed
through untouched; in particular, entity references are not resolved.
Value matching is by string equality, except that "|" in an attribute value is interpreted as an alternation character. Thus, saying
foo='red|blue' on the command line enables conditions red and blue. Saying color='black|white' in a tag matches command-line conditions
color='black' and color='white'.
Here is an example:
Always issue this text.
<?if condition='html'>
Issue this text if 'condition=html' is given on the command line.
<?elif condition='pdf|ps'>
Issue this text if 'condition=pdf' or 'condition=ps'
is given on the command line.
<?else>
Otherwise issue this text.
<?fi>
Always issue this text.
FUTURE DIRECTIONS
The mark-up used by this tool is not set in stone, and may change in the near future.
