issue while converting xml to json #686

Open priyankac1411 opened 4 years ago

priyankac1411 commented 4 years ago

when I am using this command xsltproc -o turing-machine-config.json tm-json.xsl turing-machine-config.xml

I am receiving the following errorwarning: failed to load external entity "/usr/local/share/yang/xslt/jsonxsl-templates.xsl" compilation error: file tm.xsl line 2 element include xsl:include : unable to load /usr/local/share/yang/xslt/jsonxsl-templates.xsl

I have set the environment variables PWD=/home/priya/pyang PYANG_XSLT_DIR=/home/priya/pyang/pyang/xslt MANPATH=/home/priya/pyang/man: W=/home/priya/pyang PYANG_RNG_LIBDIR=/home/priya/pyang/pyang/schema YANG_MODPATH=/home/priya/pyang/modules: PYTHONPATH=/home/priya/pyang:

This probably happens because the stylesheet tm-json.xsl was generated when the environment variable PYANG_XSLT_DIR was unset.

priyankac1411 commented 4 years ago

no, I have generated the tm-son.xsl after PYANG_XSLT_DIR was set.Can you plz help me in solving this

llhotka commented 4 years ago

Please check the <include href="..."/> element in tm-json.xsl. The value of its href attribute is set to the value of PYANG_XSLT_DIR, if it exists:

        xsltdir = os.environ.get("PYANG_XSLT_DIR",
                                 "/usr/local/share/yang/xslt")
        ET.SubElement(ss, "include", href=xsltdir + "/jsonxsl-templates.xsl")

So before generating the stylesheet, you can start Python and check the value of that environment variable:

$ python
Python 3.8.6 (default, Sep 30 2020, 04:00:38) 
[GCC 10.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ.get("PYANG_XSLT_DIR")
'/home/lhotka/Projects/pyang/xslt'
>>>

Thanx it worked . can we convert yang to xml. If yes ,then whats the procedure?

llhotka commented 4 years ago

Do you mean the conversion from JSON to XML?

@priyankac1411 for yang to xml conversion use below command: pyang -f xsd --xsd-groups --xsd-no-any-augments filename.yang

This will give you xml output.

@priyankac1411 for yang to xml conversion use below command: pyang -f xsd --xsd-groups --xsd-no-any-augments filename.yang

This will give you xml output.

The xsd plugin was supposed to produce W3C XML Schema from YANG. I believe though that this plugin is long unmaintained and doesn't really work.

JSON<->XML conversions of instance data are described in this tutorial.
