Clojure XML - is there a better way?
Hi! I struggled to use clojure.data.zip.xml in the absence of a root node. My XML looks like this: http://pmd.sourceforge.net/pmd-5.1.2/rules/java/codesize.html#TooManyMethods"; priority="3"> This class has too many methods, consider refactoring it. http://pmd.sourceforge.net/pmd-5.1.2/rules/java/codesize.html#TooManyMethods"; priority="3"> This class has too many methods, consider refactoring it. http://pmd.sourceforge.net/pmd-5.1.2/rules/java/codesize.html#ExcessiveMethodLength"; priority="3"> Avoid really long methods. ... more ... I want to extract ExcessiveMethodLength violations, and then calculate the difference between the beginline and endline attributes. Here's what I came up with: (for [x pmd-seq :when (and (= :violation (:tag x)) (= "ExcessiveMethodLength" (:rule (:attrs x))) )] (- (read-string (:endline (:attrs x))) (read-string (:beginline (:attrs x))) )) It does the job, but I feel that zip xml would have been better, but I could not figure out how to filter the data. Any insights appreciated. Thanks Adrian -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Yes good point, makes me feel the solution is maybe ok. I appreciate the feedback, thanks.

More Clojure XML challenges
I'm really struggling to understand how to parse XML in Clojure. Here's my xml: java.complexity.HelloWorld.notcomplex() 2 1 0 java.complexity.HelloWorld.complex(int) 4 2 0 ... etc I can do (xml-seq (xml/parse .. )) on this, or ( zip/xml-zip (xml/parse ... ), I don't mind which. My task is to extract all the function elements where the ncss value > 3, then sum the ccn values of the remaining elements. I simply cannot figure out how to do this. All I can do is extract text of particular elements, e.g. (apply + (map read-string (zf/xml-> ncss-zip :functions :function :ccn zf/text))) If anyone can help out, it would be much appreciated. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
