xsd2xml

This is a simple python script to help you generate some xmls if you have a xsd. It uses the xmlschema library to parse the given schema document and then populate some hardcoded values. check the following example.

XSD

<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="root" type="root"/>
  <xs:complexType name="root">
    <xs:choice>
      <xs:sequence>
        <xs:element name="empno" type="xs:string"/>
        <xs:element name="designation" type="xs:string"/>
      </xs:sequence>
      <xs:sequence>
        <xs:element name="name" type="xs:string"/>
        <xs:element name="age" type="xs:unsignedByte"/>
      </xs:sequence>
      <xs:element name="sku" type="SKU"/>
      <xs:element name="ppk" type="xs:integer"/>
      <xs:element name="alo" type="xs:date"/>
      <xs:any minOccurs="0"/>
      <xs:element name="shoesize">

            </xs:extension>
          </xs:simpleContent>
        </xs:complexType>
      </xs:element>
      <xs:element name="jeans_size">
        <xs:simpleType>
          <xs:union memberTypes="sizebyno sizebystring"/>
        </xs:simpleType>
      </xs:element>
      <xs:element name="intvalues" type="valuelist"/>
    </xs:choice>
  </xs:complexType>
  <xs:simpleType name="SKU">
    <xs:restriction base="xs:string">
      <xs:pattern value="\d{3}\w{3}"/>
    </xs:restriction>
  </xs:simpleType>
  <xs:simpleType name="sizebyno">
    <xs:restriction base="xs:positiveInteger">
      <xs:maxInclusive value="42"/>

  <xs:simpleType name="sizebystring">
    <xs:restriction base="xs:string">
      <xs:enumeration value="small"/>
      <xs:enumeration value="medium"/>
      <xs:enumeration value="large"/>
    </xs:restriction>
  </xs:simpleType>
  <xs:simpleType name="valuelist">
    <xs:list itemType="xs:integer"/>

</xs:schema>

XML

<?xml version="1.0" encoding="UTF-8"?>
<!--complex content-->
<root xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <!--START:[choice]-->
  <!--next 9 items are in a [choice] group-->
  <!--START:[sequence]-->
  <!--next 2 items are in a [sequence] group-->
  <empno>lol</empno>
  <designation>lol</designation>
  <!--END:[sequence]-->
  <!--START:[sequence]-->
  <!--next 2 items are in a [sequence] group-->
  <name>lol</name>
  <age>17</age>
  <!--END:[sequence]-->
  <sku>lol</sku>
  <ppk>-176</ppk>
  <alo>2004-04-12</alo>
  <!--next 1 item is optional (minOcuurs = 0)-->
  <_ANY_/>
  <!--simple content-->
  <shoesize>-176</shoesize>
  <!--simpletype: union.-->
  <!--default: using the 1st type-->
  <jeans_size>+3</jeans_size>
  <!--simpletype: list-->
  <intvalues>-176</intvalues>
  <!--END:[choice]-->
</root>

The command to get the above xml:

$ python xsd2xml.py -s 1.xsd -e root | xmllint --format -

Usage

$ ./xsd2xml.py -h
usage: adv.xsd2xml.py [-h] -s XSDFILE -e ELEMENT [-c]

optional arguments:
  -h, --help            show this help message and exit
  -s XSDFILE, --schema XSDFILE
                        select the xsd used to generate xml
  -e ELEMENT, --element ELEMENT
                        select an element to dump xml
  -c, --choice          enable the <choice> mode

Handle <choice>

You can generate all in a choice group (as the above example shows) or you can generate the 1st element in the choice group by the "-c" option.

command

$ python xsd2xml.py -s 1.xsd -e root -c | xmllint --format -

  <!--next item is from a [choice] group with size=9-->
  <!--START:[sequence]-->
  <!--next 2 items are in a [sequence] group-->
  <empno>lol</empno>

  <!--END:[sequence]-->
  <!--END:[choice]-->
