in reply to Regex match last

Try this. It uses @ as alternate regex-character (instead of /) and captures any (single) tag within a line.

#!/usr/bin/perl use strict; use warnings; my $data = '<c:t="AD2343"/><c:p>65677676</c:p>'; if ($data =~ m@.*(<c:[^>]*/>).*@) { print("Match: [$1]\n"); }

    This does not match the required text in the following code :

    <w:body><w:p w:rsidR="00A654E7" w:rsidRPr="00AD741F" w:rsidRDefault="00A654E7" w:rsidP="00A654E7"><w:pPr><w:pStyle w:val="Standard"/><w:rPr><w:rFonts w:asciiTheme="minorHAnsi" w:hAnsiTheme="minorHAnsi" w:cstheme="minorHAnsi"/><w:sz w:val="20"/><w:szCs w:val="20"/></w:rPr></w:pPr><w:r w:rsidRPr="00AD741F"/></w:body>

    I want only these to be matched :

    1<w:pStyle w:val="Standard"/> 2<w:rPr><w:rFonts w:asciiTheme="minorHAnsi" w:hAnsiTheme="minorHAnsi" +w:cstheme="minorHAnsi"/> 3<w:sz w:val="20"/> 4<w:r w:rsidRPr="00AD741F"/>
      show your code

      #! perl -slw use strict; m[(<[^/>]+/>)] and print "'$1'" while <DATA>; __DATA__ <w:body> <w:p w:rsidR="00A654E7" w:rsidRPr="00AD741F" w:rsidRDefault="00A654E7 +" w:rsidP="00A654E7"> <w:pPr> <w:pStyle w:val="Standard"/> <w:rPr> <w:rFonts w:asciiTheme="minorHAnsi" w:hAnsiTheme="minorHAnsi" w:cs +theme="minorHAnsi"/> <w:sz w:val="20"/> <w:szCs w:val="20"/> </w:rPr> </w:pPr> <w:r w:rsidRPr="00AD741F"/> </w:body>


      C:\test>junk23 '<w:pStyle w:val="Standard"/>' '<w:rFonts w:asciiTheme="minorHAnsi" w:hAnsiTheme="minorHAnsi" w:csthe +me="minorHAnsi"/>' '<w:sz w:val="20"/>' '<w:szCs w:val="20"/>' '<w:r w:rsidRPr="00AD741F"/>'

      BTW: Your sample XML is broken. The second level tag, <w:p ...> is never closed which will break strict XML parsers

      With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
      Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
      "Science is about questioning the status quo. Questioning authority".
      In the absence of evidence, opinion is indistinguishable from prejudice.

      The start of some sanity?

      In that case, you'll want:
      #!/usr/bin/perl use strict; use warnings; my $data = '<w:body><w:p w:rsidR="00A654E7" w:rsidRPr="00AD741F" w:rsi +dRDefault="00A654E7" w:rsidP="00A654E7"><w:pPr><w:pStyle w:val="Stand +ard"/><w:rPr><w:rFonts w:asciiTheme="minorHAnsi" w:hAnsiTheme="minorH +Ansi" w:cstheme="minorHAnsi"/><w:sz w:val="20"/><w:szCs w:val="20"/>< +/w:rPr></w:pPr><w:r w:rsidRPr="00AD741F"/></w:body>'; print "Matches found:\n" . join (",\n", $data =~ m@(<[^>]*/>)@g) . "\n +";
      Matches found: <w:pStyle w:val="Standard"/>, <w:rFonts w:asciiTheme="minorHAnsi" w:hAnsiTheme="minorHAnsi" w:csthem +e="minorHAnsi"/>, <w:sz w:val="20"/>, <w:szCs w:val="20"/>, <w:r w:rsidRPr="00AD741F"/>

      No kidding. Your original post specified <c:.../> and your current 'does not match' code uses <w:.../>. You asked for a tool to turn a cross-head screw into a board, and when given a cross-head screwdriver say 'ok, but I cannot use it to turn this slotted screw'.
