###IntelliJ IDEA Community Edition 2021.1.2 x64### ###Azul-11### Run src/test/java/org.StephanWard.utl.xml/JsonToXMLBuilderTest & XMLToJsonBuilderTest
##Additional Project Notes Provided Below for more in-depth usage###
- JSON TO XML.
- XML TO JSON.
- JSONString TO XMLString.
- JSONString TO FormattedXMLString.
- JSONObject(org.json) TO XMLString.
- XMLString TO JSONString.
- XMLString TO FormattedJSONString.
- XMLString TO JSONObject(org.json).
- Other XML Attribute Node Handle.
- JSON Converter XML.
By default, the content of a XML Tag is converted into a key called "content". This name can be changed with a custom one, using Builder.setContentName(String contentPath, String replacementName). You can change as many content names as you want.
Attributes are converted into key / values in the JSON. The attribute names may conflict with other keys. You can change the name of any attribute, by specifying the path to the attribute and the replacement name, using Builder.setAttributeName(String attributePath, String replacementName).
<?xml version="1.0" encoding="utf-8"?>
<library>
<book id="007">James Bond</book>
<book id="000">Book for the dummies</book>
</library>In a XML hierarchy, an entry can have children. For example, <library> has 2 entries <book>. In case there is only one book, there is no way to know that Book is a list. But you can force it using Builder.forceList(String path). Example shown below.
<?xml version="1.0" encoding="utf-8"?>
<library>
<book id="007">James Bond</book>
</library>By default, the <book> tag is NOT considered as a list
{
"library":{
"book":{
"id":"007",
"content":"James Bond"
}
}
}public String convertXmlToJson(String xml) {
XmlToJson xmlToJson = new XmlToJson.Builder(xml)
.forceList("/library/book")
.build();
return xmlToJson.toString();
}Now <book> is considered as a list:
{
"library":{
"book":[
{
"id":"007",
"content":"James Bond"
}
]
}
}By default the XML attributes or content are processed as Strings. If you want to force them to be another type (like Integer), then use on of these methods Builder.forceIntegerForPath(String path), Builder.forceLongForPath(String path), Builder.forceDoubleForPath(String path) or Builder.forceBooleanForPath(String path).
<?xml version="1.0" encoding="utf-8"?>
<library>
<owner>John Doe</owner>
<book id="007">James Bond</book>
<book id="000">Book for the dummies</book>
</library>public String convertXmlToJson(String xml) {
XmlToJson xmlToJson = new XmlToJson.Builder(xml)
.Builder.forceIntegerForPath("/library/book/id")
.build();
return xmlToJson.toString();
}{
"library":{
"owner": "John Doe",
"book":[
{
"id":7,
"content":"James Bond"
},
{
"id":0,
"content":"Book for the dummies"
}
]
}
}Here "007" and "000" are converted to 7 and 0.
Note that you can use forcexxxForPath methods AND change the attribute or content name for the same path; the methods in the Builder can be combined. The path used in forcexxxForPath methods is the path in the xml before eventually changing its name.
If you are not interrested in getting all the content of the XML, you can skip some Tags or some Attributes. Like for other methods you have to provide the path for the element to skip. You can use skipTag and skipAttribute as many times as you need.
<?xml version="1.0" encoding="utf-8"?>
<library>
<owner>John Doe</owner>
<book id="007">James Bond</book>
<book id="000">Book for the dummies</book>
</library>XmlToJson xmlToJson = new XmlToJson.Builder(xml)
.skipTag("/library/owner")
.skipAttribute("/library/book/id")
.build(); {
"library":{
"book":[
{
"content":"James Bond"
},
{
"content":"Book for the dummies"
}
]
}
}You may want to use XML Attributes instead of TAG content. You can do this by using the forceAttribute method. You need to specify the Path to the TAG.
{
"owner": {
"id": 124,
"name": "John Doe"
}
}JsonToXml jsonToXml = new JsonToXml.Builder(jsonObject)
.forceAttribute("/owner/id")
.build();The result becomes
<?xml version="1.0" encoding="UTF-8"?>
<owner id="124">
<name>John Doe</name>
</owner>When a Tag has only one child, you may want that child to be the Content for its parent. You can use the forceContent method to achieve this.
JsonToXml jsonToXml = new JsonToXml.Builder(jsonObject)
.forceAttribute("/owner/id")
.forceContent("/owner/name")
.build();The result becomes
<?xml version="1.0" encoding="UTF-8"?>
<owner id="124">John Doe</owner>│ .classpath
