XML to String and String to XML conversion

Use Cases Many a times, we may need to convert xml data and pass it as a string inside an XML tag. Sometimes from source, we get data which is in string format but actually is xml encoded in string format. To do so in Oracle BPEL 12c or OSB 12c we can use built in functions. XML data to String Sample input <inRoot>     <t1> Hello </t1>     <t2> World </t2>     <t3> One </t3> </inRoot> Sample output <outRoot>    <t1> &lt;inRoot&gt;&lt;t1&gt;Hello&lt;/t1&gt;&lt;t2&gt;World&lt;/t2&gt;&lt;t3&gt;One&lt;/t3&gt;&lt;/inRoot&gt; </t1> </outRoot> XSLT This can be accomplished by using the function  oraext:get-content-as-string(element as node-set) . This function is really helpful when we are working on BPEL as we can use this function in ASSIGN activity or in TRANSFORM activity using XSLT . xmlns:oraext ="http://...

Remove Empty tags using XSLT

While performing xslt transform on source XML, we may need not to include empty tags in the output xml payload.  Sample scenarios:     1.  Target system doesn't want empty tags to come.      2. Size of xml payload has become huge due to unwanted empty tags. Source XML <inRoot>     <t1>Hello</t1>     <t2></t2>     <t3>World</t3> </inRoot> Output XML <outRoot>     <a1>Hello</a1>     <a3>World</a3> </outRoot> The optimal way to achieve above result is to use conditional if statement in xslt i.e. xsl:if Sample XSLT <xsl:if test = "/inRoot/t2!=''" >      <a2>           <xsl:value-of select = "ns0:C1" />      </a2> </xsl:if> If we have some whitespaces included between tags, the above if-statement may fail and in such scenarios, we may u...

Format String oraext:format-string

In our integration world, sometimes target system requires the data from source system to be formatted in some specific format which may require data from various input fields along with custom data. To do so we generally use concat()  function to concatenate data from various fields and some user specific inputs. Lets take the below example Suppose we have a predefined format for the output string: The abc with employeeID: 1234567 has been successfully registered in the system. Here, name of the employee( $empName ='abc') and employee id( $empId ='1234567') are dynamic values. One way to accomplish this, is to use concat(). concat('The ', $empName ,' with employeeID: ', $empId ,' has been successfully registered in the system.') Another way we can achieve this, is using  oraext:format-string (string,string,string...) oraext:format-string ('The {0} with employeeID: {1} has been successfully registered in the system.', $empName , $empId ...

DateTime formatting using xp20:format-dateTime ()

xs:dateTime Format In XML, we generally use xs:dateTime(xs:xmlns="http://www.w3.org/2001/XMLSchema") data type to store date time data. The generic representation of date time, that is supported by xs:dateTime in xml: YYYY-MM-DDThh:mm:ss[.SSS][Z|(+|-)hh:mm] Example :  2019-09-11T10:16:31.943+05:30 Code Description Example YYYY represents a 4-digit year 2019 MM represents a 2-digit month 09 DD represents 2-digit date 11 hh represents 2-digit hours 10 mm represents minutes in 2-digits 16 ss represents seconds in 2-digits 31 SSS represents milliseconds 943 T represents time separator T Z represents UTC time zone or 0 time zone offset (+|-)hh:mm represents time zone offset +5:30 Few more valid examples : 2019-09-11T21:32:52, 2019-09-11T21:32:52+02:...

Create Delimited String from XML Nodes and Vice Versa in SOA 12c

A delimited string is a string representation of data separated by a delimiter(e.g. ","). A simple representation of the delimited string will look like. Delimited String Examples Sample-1-- Delimiter as ","        Value1,Value2,Value3   Sample-2-- Delimiter as "|"        Value1|Value2|Value3 If we want to represent the above set of delimited values in the form of an XML document under some root and parent tag. The representation will look like this. XML Example <root xmlns="http://test.com/sample/xml">   <Values>     <value>Value1</value>     <value>Value2</value>     <value>Value3</value>   </Values> </root> Sometimes we may need to convert values coming in delimited string to an xml document or vice versa. Since delimited strin...

Import and Export MDS artifacts in SOA 12c

Image
Oracle SOA-MDS (Metadata Store) repository can be used to access artifacts that can be shared among various SOA composites. For example, we have one common schema for a business fault that is consumed by various applications. Instead of having a localized copy of that schema file in each SOA composite, we can have it in a centralized repository (SOA-MDS). Another benefit of using SOA-MDS is that we can change the file at runtime and need not redeploy the complete code. While developing SOA composites, we use SOA design-time repository, later these changes can be synced to the SOA servers. In this article, we will discuss 2 ways to sync the artifacts available in the SOA design-time repository and the SOA servers. Establishing the connection to SOA-MDS in Jdeveloper. Using SOA em console or Fusion Middleware control console. Moving a file between SOA composite to SOA design-time MDS repository Let's assume, we created a businessFault.xsd which wi...
