    Summary of LFDocumentContentBuilder Script Helper Functions

    TheLFDocumentContentBuilderis a utility in ServiceNow designed to assist customers in extracting and managing translatable content from various artifacts, regardless of whether they use standard translation tables. These helper functions enable developers to systematically gather, organize, and process translatable strings within scripts, records, and multiple records, facilitating efficient localization workflows.

    Key Functions and Their Practical Use

    • initialize(version, targetLanguage, sysid, tableName): Acts as a constructor to initialize the builder with document version (e.g., "v1" for Xanadu release), target localization language, and artifact identifiers (sysid, table name).
    • processString(string, groupName, label): Adds a single translatable string as a content element grouped and labeled for easy identification.
    • processStringArray(stringArray, groupName, label): Handles multiple strings together, organizing them under the specified group and label.
    • processScript(scriptContent, groupName, label): Extracts translatable strings specifically from script code inputs that use getMessage, gs.getMessage, or gs.getMessageLang functions, enabling localization of dynamic script text.
    • processTranslatableFieldsForSingleRecord(glideRecord, groupName): Automatically extracts and creates elements for all translatable fields (including translatedfield, translatedtext, translatedhtml types) within a single GlideRecord, grouped for clarity.
    • processTranslatableFieldsForMultipleRecords(tableName, encodedQuery, groupName): Fetches multiple records based on a query and processes all their translatable fields collectively.
    • processElement(element): Allows manual addition of a prepared LFDocumentContentElement to the document content.
    • build(): Completes the content building process and returns the LFDocumentContent object. Note that the older getFinalJSON method is deprecated as of the Xanadu release.

    Practical Examples

    • Building Document Content: Instantiate the builder, process translatable fields for a single record, create fields and elements, add them to the builder, and finally call build() to obtain the LFDocumentContent object ready for localization workflows.
    • Extracting Translated Data: Use the generated LFDocumentContent object to iterate over its elements and fields, retrieving original and translated values for further processing or storage.

    Why This Matters to ServiceNow Customers

    This set of helper functions streamlines the extraction and packaging of localized content from diverse sources within ServiceNow, reducing manual effort and errors. It supports complex scripts and multiple record scenarios, ensuring that all translatable content is identified and structured consistently. By using these APIs, customers can accelerate their localization projects, maintain translation quality, and integrate smoothly with ServiceNow’s localization framework.

    The LFDocumentContentBuilder provides utility functions to build document content. Use these functions to write the logic to extract the translatable content from any artifacts regardless of them using standard tables or not for translations.

    initialize (version, targetLanguage, sys_id, tableName)

    Use this function as a constructor for LFDocumentContentBuilder and includes the following parameters:
    Name Type Description
    Version String The version type of the document content to be generated. For Xanadu, this value is v1.
    targetLanguage String The target language of the localization task document content.

    The target language is the same as the language available from the read script function argument.

    Sys_id String The sys_id of the artifact record.
    tableName String The table name of the artifact record.

    processString (string, groupName, label)

    Use this function to add the LFDocumentContentElement in the document content for the given string and includes the following parameters.
    Name Type Description
    string String The value for which a document content entry is created.
    groupName String The name of the group to which element should belong.
    label String The unique label identifier for the created element.

    processStringArray (stringArray, groupName, label)

    Use this function to add elements (object of LFDocumentContentElement) in the document content for the given strings and includes the following parameters.
    Name Type Description
    stringArray List of Strings The list of values for which document content entry is created.
    groupName String The name of the group these strings belongs to.
    label String The unique label identifier for these strings.

    processScript (scriptContent, groupName, label)

    Use this function to add an element in the document content for the strings present as input of getMessage, gs.getMessage, or gs.getMessageLang in the provided Script. It has the following parameters:
    Name Type Description
    scriptContent String The Script to be processed to get the strings present as input of getMessage, gs.getMessage, or gs.getMessageLang.
    groupName String The name of the group for this input.
    label String The unique label identifier for this input.
    For example,
    var documentContentBuilder = new LFDocumentContentBuilder("v1", language, sysId, tableName);
    Var name = "name";
    documentContentBuilder .processScript("gs.getMessage('Hello {0}, How are you', name)", "Script_Group", "Script_Label");

    processTranslatableFieldsForSingleRecord (glideRecord, groupName)

    Use this function to create elements for the given glideRecord object, in document content for all its translatable fields. These translatable fields can be of translated_field, translated_text or translated_html types. It includes the following parameters:
    Name Type Description
    glideRecord GlideRecord The GlideRecord object to be processed for translatable fields. The GlideRecord should be pointing to the valid table record.
    groupName String The name of the group for this input.

    processTranslatableFieldsForMultipleRecords (tableName, encodedQuery, groupName)

    Use this function to fetch all the qualified records for the given tableName and encodedQuery and adds elements (object of LFDocumentContentElement) in the document content for all the translatable fields. It includes the following parameters:
    Name Type Description
    tableName String The table to fetch records.
    encodedQuery String The encoded query for filtering records from the processTranslatableFieldsForSingleRecord table.
    groupName String The name of the group for this input.

    processElement()

    Use this function to add an element (object of LFDocumentContentElement) to LFDocumentContent object.
    element LFDocumentContentElement Element to be added to the document content.

    build()

    Returns the LFDocumentContent object.

    Note:
    The getFinalJSON function has been deprecated in the Xanadu release and it is recommended to use the build() function.
    A sample script to build the document content.
    getTranslatableContent: function(params) {
        var tableName = params.tableName;
        var sysId = params.sysId;
        var language = params.language;
        var lfDocumentContentBuilder = new global.LFDocumentContentBuilder("v1", language, sysId, tableName);
        // This will create a new object of LFDocumentContent and stores it internally
        lfDocumentContentBuilder.processTranslatableFieldsForSingleRecord(gr, "Basic Info");
        var field = LFDocumentContentHelper.createField(originalValue, translatedValue);
        field.setTextType(LFDocumentContentHelper.PLAIN_TEXT_TYPE);
        // All the other relevant attributes can be set
        var element = LFDocumentContentHelper.createElement(groupName, label);
        element.addField(field);
        lfDocumentContentBuilder.processElement(element); // Adds element to the LFDocumentContent object
        return lfDocumentContentBuilder.build(); // return the LFDocumentContent object
    }
    

    Sample script to extract data from the LFDocumentContent

    saveTranslatedContent: function(documentContent) {
        // LFDocumentContent object is passed as an argument to the saveTranslatedContent 
        var targetLanguage = documentContent.getLanguage();
        var version = documentContent.getVersion();
        var elements = documentContent.getElements(); // Array of LFDocumentContentElement objects
        for (var idx = 0; idx < elements.length; idx++) {
            var element = elements[idx];
            var groupName = element.getGroupName();
            var fields = element.getFields(); // Array of LFDocumentContentField objects
            for (var fieldIdx = 0; fieldIdx < fields.length; fieldIdx++) {
                var field = fields[fieldIdx];
                var originalValue = field.getOriginalValue();
                var translatedValue = field.getTranslatedValue();
                // Get all the other required members and process them appropriately
            }
        }
    }
