This python module provides possibilities to convert XML to JSON vice versa through a conversion manager.
Information about this module can be found here:
This module will require the following python modules to operate:
- jk_temporary - License: Apache 2.0
- dicttoxml - License: GPL2
- xmltodict - License: MIT
To import this module use the following statement:
import jk_xmljsonconvIt is very simple to prepare the main converter object for use:
c = jk_xmljsonconv.FormatConverter(tempDirPath)The variable tempDirPath must provide an exsting and empty directory. Here temporary files required during conversion will be stored.
Files created in this temporary directory will be provided to the caller. If you request a file from the converter it will create one for you. It is your resposibility to move the file to whichever place you want it to be after the conversion process. (Or delete the file if you decide to not use the file any more.)
To get an overview about what kind of conversions are supported, run the following code:
print("The following formats are supported: " + str(c.listFormats()) + "\n")
print("The following format conversions are supported: " + str(c.listConversions()) + "\n")This will output something like this:
The following formats are supported: ['json', 'jsonfile', 'jsonstr', 'xml', 'xmlfile', 'xmlstr']
The following format conversions are supported: ['json->jsonfile', 'json->jsonstr', 'json->xml',
'json->xmlfile', 'json->xmlstr', 'jsonfile->json', 'jsonfile->jsonstr', 'jsonfile->xml', 'jsonfile->xmlfile',
'jsonfile->xmlstr', 'jsonstr->json', 'jsonstr->jsonfile', 'jsonstr->xml', 'jsonstr->xmlfile',
'jsonstr->xmlstr', 'xml->json', 'xml->jsonfile', 'xml->jsonstr', 'xml->xmlfile', 'xml->xmlstr',
'xmlfile->json', 'xmlfile->jsonfile', 'xmlfile->jsonstr', 'xmlfile->xml', 'xmlfile->xmlstr',
'xmlstr->json', 'xmlstr->jsonfile', 'xmlstr->jsonstr', 'xmlstr->xml', 'xmlstr->xmlfile']
The file formats supported are:
| File Format ID | Data Type | Description |
|---|---|---|
| json | json-object | An object that can be a used as a JSON data structure in memory. |
| jsonfile | string | The file path of a JSON file. |
| jsonstr | string | The JSON data provided as a string. |
| xml | xml-object | An object that can be a used as an XML data structure in memory. |
| xmlfile | string | The file path of an XML file. |
| xmlstr | string | The XML data provided as a string. |
The file conversion IDs are built from these IDs.
It is very easy to perform a conversion:
resultData = str(c.convert1(convID, inputData))F.e. if you provide an XML string this could look like this:
SOME_XML_INPUT = "<?xml version=\"1.0\"?><html><body><h1>Some heading</h1><div><p>Some text.</p></div></body></html>"
resultData = str(c.convert1("xmlstr->jsonstr", SOME_XML_INPUT))With resultData containing the following string after conversion:
{"html":{"body":{"h1":"Some heading","div":{"p":"Some text."}}}}
The next lines declare the methods the FormatConverter class will provide:
#
# Constructor method.
#
# @param object tempDir Either provide a directory path here for temporary files or a <c>TempDir</c> object.
#
def __init__(self, tempDir)#
# Get a list of formats supported.
#
# @return string[] Returns a list of IDs.
#
def listFormats()#
# Get a list of all conversions supported.
#
# @return string[] Returns a list of IDs.
#
def listConversions()#
# Convert the input data.
#
# @param string convID A conversion ID such as f.e. "xmlstr->jsonstr".
# @param object inputData The input data. The type of this data must correlate with the source format type specified.
# @return object The result data. The type of this data will depend on the conversion specified.
#
def convert1(convID, inputData)#
# Convert the input data.
#
# @param string fromFormat The source format of the conversion.
# @param string toFormat The target format desired.
# @param object inputData The input data. The type of this data must correlate with the source format type specified.
# @return object The result data. The type of this data will depend on the conversion specified.
#
def convert2(fromFormat, toFormat, inputData)#
# Get a converter by conversion ID.
#
# @param string convID A conversion ID such as f.e. "xmlstr->jsonstr".
# @return AbstractConverter Eiter returns <c>None</c> if no converter is available or the converter object that performs the conversion.
#
def getConverter1(convID)#
# Get a converter by conversion ID.
#
# @param string fromFormat The source format of the conversion.
# @param string toFormat The target format desired.
# @return AbstractConverter Eiter returns <c>None</c> if no converter is available or the converter object that performs the conversion.
