Hi,
I have a bunch of sentences in a file and I want to match the Nouns Phrases, which are between these delimiters <NP#>...</NP> and substitute (delete) -in the noun phrase-, all the tags, to add only one tag "/NP" on the last word of the phrase. This for each sentence... 
<S> Who/WP is/VBZ <NP1> the/DT author/NN </NP> of/IN <NP2> the/DT book
+/NN </NP> ,/,/*comma* "/"/*\
quote* <NP3> The/DT Iron/NNP Lady/NNP </NP> :/: <NP4> A/DT Biography/N
+NP of/IN \Margaret/NNP That\
cher/NNP </NP> "/"/*quote* ?/./*end-of-sentence*</S>

Result: 
<S> Who/WP is/VBZ  the author/NP of/IN  the book/NP ,/,  The Iron Lady
+/NP :/:   A  Biography of Margaret That\
cher/NP  "/"...

So far, I am getting nothing with the match, no even with the replacement 
 if ($sentence =~ / (<NP\d*>) ([a-zA-Z0-9.-_]+)\/([A-Z]+) ([^ ]+) (<\/
+NP>) /) {
    $text="NounPhrase";    # to test the match to replace 
    $result =~ s/$question/$text/;
    print "$result";};

Thanks in advance for your help
