class HS.Util.XSLTHelper extends %XML.XSLT.CallbackHandler

This class handles callbacks from the XSLT processor. You should create a subclass this class and override the 'evaluate' method to perform the processing that you require. An example of an stylesheet using this function is shown in the example XSL contained in the %XML.XSLT.Transformer class

Method Inventory


classmethod ReportAccess()
classmethod ResetAccess()
classmethod createHL7Timestamp() as %String
classmethod createID(pPrefix As %String = "") as %String
Create a generic XML element ID unique for the current transform, with optional prefix
classmethod createOID() as %String
classmethod createUUID() as %String
classmethod dateDiff(pDatePart As %String = "", pStartDateODBCFormat As %String = "", pEndDateODBCFormat As %String = {$ZDateTime($Horolog, 3)}) as %Integer
classmethod dateNoDash(pDate) as %String
method evaluate(Args...) as %String
Inherited description: Evaluate receives a variable number of arguments, allowing you to pass multiple arguments on the evaluate call. The number of arguments is available in the Args variable and each value can be accessed by subscripting. The method has a single return value which will be returned as the result of the xslt evaluate function(). The return value can either be a regular cache variable or it can be an instance of a stream object. This allows for returning a value that is greater than 32k in size. The stream has to be wrapped in an instance of %XML.XSLT.StreamAdapter which facilitates the XSLT processors reading of the stream. This example shows both techniques, change the 1 to 0 to test the stream functionality (%XML.XSLT.Transformer.Example3() exercises this functionality)
classmethod getCodeForOID(pOID As %String = "", pType As %String = "", pDefault As %String = "") as %String
classmethod getCodeForURL(pURL As %String = "", pType As %String = "", pDefault As %String = "") as %String
classmethod getCodedEntryConfig(pCodeType As %String = "", Args...) as %String
Return the most specific coded entry XSL nodes for the given coded entry type as code^desc^scheme
classmethod getConfigValue(pKey As %String = "") as %String
Return a registry config value for the given key
classmethod getDescriptionForOID(pOID As %String = "", pType As %String = "", pDefault As %String = "") as %String
classmethod getDescriptionForURL(pURL As %String = "", pType As %String = "", pDefault As %String = "") as %String
classmethod getHierarchicalConfigValue(pKey As %String = "", Args...) as %String
Return the most specific registry config value for the given root and children For example here are some outputs given the following keys: \a = apple \a\b = banana \a\b\c = carrot \a\\c = cucumber getHierarchialConfigValue("\a",,,"b","c") -> carrot getHierarchialConfigValue("\a",,,"b") -> banana getHierarchialConfigValue("\a",,,"x","y") -> apple getHierarchialConfigValue("\a",,,"","c") -> cucumber This is used by the XDSb Document metadata generator transform to allow overriding coded entries (aka Classifications) based on context

classmethod getPreviousUUID(pDocKey As %String = "") as %String
DEPRECATED -- This method is no longer supported by InterSystems and will be removed Return the UUID of the previous submission for the given document key, if any
classmethod getQuickStream(pStreamId) as %String
Method to return the contents of a quickstream. For security purposes, the stream ID must be one explictly labeled as one to be passed into here, starting with TXSLTHelper (perhaps followed by $J)

Return a domain and URL (e.g., http://host:port/url) given an OID
classmethod getSystemOID(pSystem As %String = "") as %String
classmethod getURLForCode(pCode As %String = "", pType As %String = "", pDefault As %String = "") as %String
classmethod getUniqueTime(pKey As %String = "", pValue As %String) as %String
Work around for bug in viewer that looses documents with same date/time over different encounters It will return a unique timestamp for the current transform as close to the input timestamp as possible
classmethod hex2dec(pHex As %String = "") as %String
Convert a hexidecimal number to decimal While $ZHEX has a max hex input length of 16, this method has no limit -- only cpu/ram will affect max input length
