Saxon-Node: Modern XSLT, XQuery and XPath in Node.js

zakes 8年前



An exploration of binding Saxon/C (XSLT 2.0/3.0, XQuery 1.0/3.0, Schema Validation 1.0/1.1 and XPath 2.0/3.0).

Note: A major API change is in progress. The method names are being upgraded to mirror . New functionality is being exposed.

Note: release v0.1.1 is built with nodejs v4.2.x [v4.2.x has Buffer acting like Uint8Array and currently is indistinguishable on the native side yet seems to work for this project]. If you want v0.12.x compatibility stay with v0.0.5. npm will continue with nodejs v4.2.x line and any fixes or features needed by prior versions will be from github branches.

To tell it where the Saxon/C is set the environment variable SAXONC_HOME to path:

export SAXONC_HOME=/home/user/Software/Saxonica/Saxon-HEC1.0.0


linux-x64,linux-ia32, darwin-x64 and win32-ia32.

npm install --fallback-to-build

will first try to find a compatible native prebuilt. If it works you won't need development tools and compilers.

Building (only if needed; contact me if there is a particular prebuild you would use)

If a compatible prebuilt is not found, a number of environment variables are needed. For the build phase, as with integrating Saxon/C interface code in c/c++ applications the jni.h is needed. Set JAVA_HOME and the binding.gyp locates the jni.h from there. Only the headers are used; that comes wth Saxon/C is loaded from it's home folder. The depends on $SAXONC_HOME/rt during runtime and it needs library paths $SAXONC_HOME:$SAXONC_HOME/rt/lib/amd64/jetvm:$SAXONC_HOME/rt/lib/amd64. rt is the runtime that Saxon/C provides. Note: The SAXONC_HOME needs to

To run it needs the harmony switch and at least nodejs v4.2.x. Make sure there isn't a java path to jvm in front of the Excelsior JET tool in rt folder:

export LD_LIBRARY_PATH=$SAXONC_HOME:$SAXONC_HOME/rt/lib/amd64/jetvm:$SAXONC_HOME/rt/lib/amd64:$LD_LIBRARY_PATH  node --harmony saxon-node.js /home/user/testing-grounds/BCL/analyze.xml /home/user/NetBeansProjects/OOBackbone/stylesheets/divconIsSpecies.xsl

Yet this isn't the purpose to run xslt as this small app. The intention is the calling of the API from your applications.

To test

export LD_LIBRARY_PATH=$SAXONC_HOME:$SAXONC_HOME/rt/lib/amd64/jetvm:$SAXONC_HOME/rt/lib/amd64:$LD_LIBRARY_PATH  mocha --harmony --require should
