Examples

The following example shows the situation if the document contains “Invoice Number INV-12345” then template field can be defined in the following way:

// Create a regex template field with "InvoiceNumber" name
TemplateField templateField = new TemplateField(
    new TemplateRegexPosition("Invoice Number\\s+[A-Z0-9\\-]+"),
    "InvoiceNumber");

In this case as a value the entire string is extracted. To extract only a part of the string the regular expression group “value” is used:

// Create a regex template field with "InvoiceNumber" name with "value" group
TemplateField templateField = new TemplateField(
    new TemplateRegexPosition("Invoice Number\\s+(?<value>[A-Z0-9\\-]+)"),
    "InvoiceNumber");

In this case as a value “INV-3337” string is extracted.
