This page lists the most frequently used Nodes according to category. If you've just started with Flowgear, it's a good idea to take a quick read through it.
There are a large number of other Nodes (including Connectors) that are not linked here. The full list of Node is presented in the Node Choose Popup in the Console.
Choose - Enables branching of execution flow based on an expression.
Error - Throw custom exceptions (errors) within the Workflow.
If - Control process flow by evaluating an expression.
Loop - Create a set number of iterations of a task. Also see Loop Exit.
Splitter - Split XML into sections using XPath and iterate over each section.
Validate - Evaluates a set of properties against a set of validations.
Variable Bar - Create a Data Contract for your workflow by defining a set of variable inputs and outputs.
Workflow - Executes a sub-workflow. This enables you to develop highly-reusable workflows and is comparable to calling a method in code.
JSON Request - Execute a Web Request that takes a JSON payload and returns a JSON response.
Soap Request - Execute a SOAP Request by populating the Envelope Header and Body. The raw SOAP Response is returned.
Web Request - Execute a Web Request.
Transforming and Analysing Data
JSON Convert - Convert between JSON and XML.
LINQ - Transform data using a .NET LINQ expression against a data source.
QuickMap - Visually Data Mapper - enables transformation of source data so it's appropriate for a target endpoint.
XML Merge - Merge one XML document into another by matching rows on corresponding values.
XML Replace -| Replace multiple brace-encapsulated tags in a string template using an XML Document as a replacement dictionary.
XPath Match - Return a match on an XPath in an XML document.

String Builder - Provides a mechanism for appending strings to a variable that can be accessed from anywhere in the Workflow.
Substring - Returns a substring by offset or by matching start and end expressions.
Expression - Evaluates a C#-style expression, allowing you to query values of other Node Properties in code.
PDF Parser - Returns text from a PDF document.
Script - Executes arbitrary C# code, allowing you to query and set values of other Node Properties in code. Also support Custom Properties.
SQL Query - Executes a SQL query against a SQL Server instance. For other types of SQL databases, look at ODBC Query and OLEDB Query
SQL Table Update - Performs a bulk update and/or insert of data in a SQL Server database table. For other types of SQL databases, look at ODBC Table Update and OLEDB Table Update
Email & SMS
Email Alert - Sends an alert from [email protected] to the designated recipients.
Email Watcher - Polls a mailbox via POP for new email. Also consider IMAP Watcher to monitor a specific mailbox folder using IMAP.
Single Email - Sends an email via SMTP using the provided SMTP server and credentials.
SMS Out - Sends an SMS.
Deduplicator - Removes duplicate data in an XML document by evaluating matches on an XPath.
Reducer - Removes data from an XML document that has been previously processed by evaluating hashes on XPath matches.
Windows Filesystem & FTP
File - Reads and writes files as text or binary.
Flat File - Converts a delimited or fixed-width file to XML, also converts XML to fixed-width or delimited.
File Watcher - Monitors a filesystem or FTP folder for new or modified files.
Multi Record Flat File - Parse a multi-record flat file to XML or render an hierarchical XML document to a multi-record flat file.
Cache and Statistics
Cacher - Store information in Flowgear Cache for fast acquisition of frequently accessed data.
Query Statistic - Query a range of data stored in Flowgear Statistics.
Statistic - Record progressive transaction or entity status in Statistics for unified analysis and reporting.
