in thread Check tag value
Hi,
you're code:
should be something like:if ( $Lines eq "<NumberofDays>\d+</NumberofDays>" )
3 differences between your and my line:if ( $Lines =~ m|<NumberofDays>(\d+)</NumberofDays>| )
- eq vs. =~ to compare against a regular expression you use =~
- the regular expression is in 'm|' and '|' characters This is to make clear you are using a regular expression
- the \d+ is in '(' and ')' characters This is used to 'capture' the value of the expression inbetween them. In this case it would capture the value in $1. The rule is the first ()-match is captured in $1, the second in $2 etc. So in your code you could continue with something like
Hope this helps getting you started. For documentation on regular expressions there are 2 good tutorials that come with perl that were not mentioned here: perlrequick perlretutprint $1
