Parsing xml?
Locked
 
|
Looking for pointers (examples preferably) on parsing xml in NetRexx.
The task is formatting MQFTE transfer log msgs. This was done historically by a set of java pgms whose origin I'm unfamiliar with. Following one upgrade several years ago of the command-and-coordinator qmgr from MQ v7.5 to v8.0, the xml parser ('log reporter') was throwing errors on logger msgs produced by FTE agents that were also upgraded. My java cluelessness (& other resource constrictions) resulted in me cobbling together an alternate parser using shell script examples freely available. I struggled to comprehend how the java solution functioned, and my attempts at inserting debug stmts just broke it - throwing me at the quick-n-dirty shell script option. You know how deadlines loom. However, while it works & at least I can understand it, it's SLOW. So, the goal is to return to a better performing java based MQFTE log reporter by means of NetRexx. I've often thought there must be a NetRexx xml parser solution out there somewhere. Does such a tool exist? Peter BTW, MQ upgrades to v9.1 are well under way. _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/ |

Not sure this will help you, but may enable you to take advantage of Java-SAX and/or Java-DOM solutions from NetRexx, by rewriting/recoding the BSF4ooRexx examples in NetRexx. If you do, I would be very interested in them of course! :)
If you have ooRexx and install BSF4ooRexx you would find the ooRexx samples to transcribe to NetRexx in the "samples/SAX" and "samples/DOM" subdirectories. --- Again, IMHO, the fastest/easiest route is probably via SAX. HTH, ---rony [1] "Simple API for XML":

Unfortunately, a bsf4ooRexx install didn't yield the promised samples (this time). Have I missed something? Below is the result of searches for the samples, SAX & DOM dirs, plus a search for any *.rxj files under the bsf4ooRexx install dir. -------------------------------- [psharp@fedora NetRexx]$ find bsf4ooRexx -name samples _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/ |

your last output (path to test.rxj), the samples directory should
be in "bsf4ooRexx/BSF4ooRexx_testUnits/samples" on your machine. If you had installed BSF4ooRexx on a Linux machine, it should be
in "/opt/BSF4ooRexx/samples". Alternatively, you could look them up starting out pointing your
browser at:
<https://sourceforge.net/p/bsf4oorexx/code/HEAD/tree/trunk/samples/>. HTH, ---rony

Follow along with NetRexx

Thanks Jason! As expected, the nrx solution is so much more elegant than
java :-) Seeing the flavours of xml parsing listed there, what I actually need is an nrx version of the convert-xml-to-properties function. Should keep me busy for a while.

Second verse same as the first. tweak args=String[], types and
directories. _______________________________________________ Ibm-netrexx mailing list [hidden email] Online Archive : http://ibm-netrexx.215625.n3.nabble.com/ |

Well, I have the beginnings of an xml parser, thanks to Rony & Jason!
