XML Functions

XML functions are typically used in transformation mapping scripts that require the manipulation and access of XML data.

Attribute

Declaration

type Attribute(string attributeName, string attributeValue)

Syntax

Attribute(<attributeName>, <attributeValue>)

Required Parameters

• attributeName:  Attribute name
• attributeValue:  Attribute value

Description

Creates an attribute for an XML node. See also the CreateNode() function.

Examples

// Adds an attribute "name" with a value of "value"
Attribute("name","value");

CreateNode

Declaration

string CreateNode(string namespace, string nodeName, type attributeSubelement[,...])

Syntax

CreateNode(<namespace>, <nodeName>, <attributeSubelement>[,...])

Required Parameters

• namespace:  The namespace of the node
• nodeName:  Name of the node
• attributeSubelement:  A subelement: a value, attribute, or sub-node

Optional Parameters

• attributeSubelement:  Additional subelements (a value, attribute, or sub-node), as required

Description

Creates a string representing an XML node. If the target node is the value node of an XML Any node, an XML element corresponding to the nodeName and nodeValue will be created.

Starting from the third argument, a series of values, attributes, and sub-nodes can be specified. Values are specified directly. Attributes and sub-nodes can be created with the  Attribute()  and  CreateNode()  functions respectively.

Examples

// Creates a node with a sub-node
CreateNode("http://example.com/xml",
    "Contact", "Bill  G.", Attribute("Type", "VIP"), 
    CreateNode("http://example.com/xml",
        "Title", "Manager")
    );

GetNodeName

Declaration

string GetNodeName(type path)

Syntax

GetNodeName(<path>)

Required Parameters

• path:  A path expression that selects a single node

Description

Retrieves the name of a node. This method is typically used to retrieve the name of a node returned by either of the SelectNodeFromXMLAny()  or  SelectSingleNode()  functions.

Examples

// Retrieves the name of a node
GetNodeName(SelectNodeFromXMLAny("Account", Root$Any.));

GetNodeValue

Declaration

string GetNodeValue(type path)

Syntax

GetNodeValue(<path>)

Required Parameters

• path:  A path expression that selects a single node

Description

Retrieves the value of a node. This method is typically used to retrieve the value of a node returned by either of the SelectNodeFromXMLAny()  or  SelectSingleNode()  functions.

Examples

// Retrieves the value of a node
GetNodeValue(SelectNodeFromXMLAny("Account", Root$Any.));

GetXMLString

Declaration

string GetXMLString(type path[, bool qualified])

Syntax

GetXMLString(<path>[, <qualified>])

Required Parameters

• path:  A path expression that selects a single node

Optional Parameters

• qualified:  A boolean value (default false); when qualified (true), the XML string returned is easier to read but may not by itself be valid XML

Description

Returns (when used in a Formula Builder mapping) the corresponding XML string found in the source XML document at the specified path.

To enter a path into the function, you can double-click on the desired XML node folder to insert its qualified path at the location of your cursor. See the instructions on inserting XML node paths.

Examples

// Retrieves the corresponding XML string at the specified path
GetXMLString([Header$DETAIL.]);

IsNil

Declaration

bool IsNil(string path)

Syntax

IsNil(<path>)

Required Parameters

• path:  A path expression that selects a single node

Description

Returns (when used in a Formula Builder mapping) if the corresponding XML node has the attribute "xsi:nil" with the value of true (or 1). 

To enter a path into the function, you can double-click on the desired XML node folder to insert its qualified path at the location of your cursor. See the instructions on inserting XML node paths. As described in XML Schema, an element may be valid without content if it has the attribute  xsi:nil  with the value  true .

Examples

// Returns if the node is nil
IsNil("Header$DETAIL.");

RunXSLT

Declaration

array RunXSLT(string xslt, string xml1[, string xml2,... string xmlN)

Syntax

RunXSLT(<xslt>, <xml1>[, <xml2>,... <xmlN>])

Required Parameters

• xslt:  An XSLT stylesheet
• xml1...xmlN:  One or more XML documents

Description

Supports running XSLT (v1-3) on a number of input XML documents. Takes as input an XSLT stylesheet and one or more XML documents and returns an array of XML documents.

Examples

// Running XSLT on XML Files

// Read in a stylesheet
xslt = ReadFile("<TAG>Sources/XSLT</TAG>");

// Read in two XML files for processing
xml1 = ReadFile("<TAG>Sources/XML1</TAG>");
xml2 = ReadFile("<TAG>Sources/XML2</TAG>");

// RunXSLT on the stylesheet and the two XML files
output = RunXSLT(xslt, xml1, xml2);

// As RunXSLT() returns an array,
// retrieve the output from each element
i = 0;
While(i < Length(output),
  // Write output to a file
  WriteFile("<TAG>Targets/XML Output FTP</TAG>", 
    output[i], "output" + (i+1) + ".xml");
  i++;
);

Jitterbit-specific Concepts

Using an existing XSLT Transform

It is also possible to use an existing XLST Transform as the first argument to RunXSLT(). An XLST Transform is defined as a separate entity from the script and can be reused in multiple scripts and XLST Transform operations. This must be an XLST Transform defined in the current project. See the instructions on inserting project items.

// Runs an existing XSLT Transform, passing values
// using variables customers, salesPeople, salesOrders
mergedOut = RunXSLT("<TAG>XSLT Transforms/Merge Transform</TAG>", 
    customers, salesPeople, salesOrders);

Referring to Files from within an XSLT Stylesheet

While Jitterbit has broad support for XSLT, projects that use XSLT must follow rules to pass the security standards. These rules mean that access to files or URIs must always be through the use of sources and targets defined in the same project.

To reference these files or URIs in a stylesheet, use the XLST fn:doc function and specify 'param1' for the first XML input, 'param2' for the second XML input, and so on for each additional XML file.

For this example, given the previous example of processing three XML files (customers, salesPeople, salesOrders), you could refer to them in an XSLT stylesheet using:

<xsl:for-each select="doc('param1')/*:Customers/*:SalesOrder[customer_external_id!=''][sales_person_external_id!='']">
...
<xsl:for-each select="doc('param2')/*:SalesPeople/*:Account[*:customer_id/string(number(text()))=$CustomerExtId][1]">
...
<xsl:for-each select="doc('param3')/*:SalesOrders/*:SalesOrder[customer_external_id!=''][sales_person_external_id!='']">

If you have a single input XML file, it is not required to use the  doc('param1') syntax as Jitterbit will set the initial context to that single file.

Specifying a Starting Template in the Stylesheet

In some situations, Jitterbit needs to know where in a stylesheet to begin processing. This is achieved by including in the stylesheet a template with the specific name of start_here:

<xsl:template name="start_here" match="/">

SelectNodeFromXMLAny

Declaration

type SelectNodeFromXMLAny(string nodeName, type anyNodes)

Syntax

SelectNodeFromXMLAny(<nodeName>, <anyNodes>)

Required Parameters

• nodeName:  The desired node name
• anyNodes:  The data element path of a value node of an XML Any element or an array of XML nodes

Description

Returns the first XML node from a list of XML Any nodes that match the node name.

Examples

// Looks for the first node that matches "Account"
SelectNodeFromXMLAny("Account", Root$Any#.);

SelectNodes

Declaration

array SelectNodes(type node, string xPathQuery[, string xPathArg1,... string xPathArgN])

Syntax

SelectNodes(<node>, <xPathQuery>[, <xPathArg1>,... <xPathArgN>])

Required Parameters

• node:  The desired node or XML fragment to run the query on
• xPathQuery:  The data element path of a value node of an XML Any element

Optional Parameters

• xPathArg1...xPathArgN:  Prefixes specifying the namespaces of nodes in the XPath query

Description

Runs an XPath query (see the XPath standard, v1-v3) on either an XML fragment or an XML node returned from another function, and returns the results of the query.

If the optional prefixes are used to specify the namespaces of the node in the XPath query, the prefixes must be specified as one or more string arguments after the XPath (see the second example).

Examples

// Connects to an LDAP server, runs a search,
// and then runs an XPath Query on the results
LDAPConnect("directory.company.example.com","ghvwright","1LikesPe@ches",0);
searchResults = LDAPSearch("CN=Users,DC=company,DC=example,DC=com",
    "(&(objectCategory=person)(objectClass=user))", 1, 
    "name", "whenCreated", "description", "telephoneNumber");  
resultNodes = SelectNodes(searchResults,
    "/DirectoryResults/Entry[name='Administrator']/whenCreated" );

SelectNodes(Root$Any$, 
    "ns1:E2/ns2:E3",
    "ns1=http://xyz1.example.com/",
    "ns2=http://xyz2.example.com/");

SelectNodesFromXMLAny

Declaration

array SelectNodesFromXMLAny(string xPathQuery, type anyNodes[, string xPathArg1,... string xPathArgN])

Syntax

SelectNodesFromXMLAny(<xPathQuery>, <anyNodes>[, <xPathArg1>,... <xPathArgN>])

Required Parameters

• xPathQuery:  An XPath query
• anyNodes:  The data element path of a value node of an XML Any element or an array of XML nodes

Optional Parameters

• xPathArg1...xPathArgN:  Prefixes specifying the namespaces of nodes in the XPath query

Description

Returns an array of all the XML nodes that are matched by an XPath query (see the XPath standard, v1-v3) run against either a path of a value node of an XML Any element or an array of XML nodes.

If the optional prefixes are used to specify the namespaces of the node in the XPath query, the prefixes must be specified as one or more string arguments after the XPath (see the second example).

Examples

// Select all the nodes with the given names  
SelectNodesFromXMLAny("Account|Customer|Name", Root$Any#.);

// Select email addresses and phone numbers only 
$nodes = SelectNodesFromXMLAny("cust:EmailAddress|cust:PhoneNumber",
    Customer$Any#., "cust=urn:xmlns:25hoursaday-com:customer");

SelectSingleNode

Declaration

type SelectSingleNode(type node, string xPath,...)

Syntax

SelectSingleNode(<node>, <xPath>,...)

Required Parameters

• node:  The desired node or XML fragment to run the query on

• xPathQuery:  The data element path of a value node of an XML Any element

Optional Parameters

• xPathArg1...xPathArgN:  Prefixes specifying the namespaces of nodes in the XPath query

Description

Runs an XPath query (see the XPath standard, v1-v3) on either an XML fragment or an XML node returned from another function, and returns the first node in the results of the query.

If the optional prefixes are used to specify the namespaces of the node in the XPath query, the prefixes must be specified as one or more string arguments after the XPath (see the second example).

Examples

// Connects to an LDAP server, runs a search,
// runs an XPath Query on the results, and 
// selects the first node in the query results
LDAPConnect("directory.company.example.com", "ghvwright", "1LikesPe@ches", 0);
searchResults = LDAPSearch("CN=Users,DC=company,DC=example,DC=com",
    "(&(objectCategory=person)(objectClass=user))", 1, "name", 
    "whenCreated", "description", "telephoneNumber");
resultNode = SelectSingleNode(searchResults,
    "/DirectoryResults/Entry[name='Administrator']/whenCreated");

// Selects the first node in an XPath query result.
// The reference node is an XML node for an XML Any node.
// In the XPath query, "ns1:E2" is not the reference node itself.
// Since the prefixes ns1 and ns2 are used in the XPath query,
// they are defined as additional arguments after the XPath.
SelectSingleNode(Root$Any$,
    "ns1:E2/ns2:E3",
    "ns1=http://xyz1.example.com",
    "ns2=http://xyz2.example.com/");
