Class MailMerger

java.lang.Object
org.docx4j.model.fields.merge.MailMerger
Direct Known Subclasses:
MailMergerWithNext
public class MailMerger extends Object
Perform a mail merge. Instance values are merged into a docx containing MERGEFIELD to produce output docx made up of a copy of the input docx for each collection of input values. The output can be a single docx, or multiple docx. If you choose single docx, there are two ways to do this: One is using MergeDocx, which will ensure each constituent "document" doesn't affect the neighbouring ones (eg numbering will restart). The other is the "poor man's" approach, which puts them together, and just hopes for the best. Images and hyperlinks should be ok. But numbering will continue, as will footnotes/endnotes. From 3.0, there is some support for formatting switches (date/time, numeric, and general), and basic support for MERGEFORMAT. LIMITATIONS: - no support for text before (\b) and text after (\f) switches - no support for \m and \v switches - no support for multiple MERGEFIELD in a single instruction (eg MERGEFIELD CoutesyTitle \f " " MERGEFIELD FirstName \f " " MERGEFIELD LastName )

    • getConsolidatedResultCrude

      public static WordprocessingMLPackage getConsolidatedResultCrude(WordprocessingMLPackage input, List<Map<DataFieldName,String>> data) throws Docx4JException
      A "poor man's" approach, which generates the mail merge results as a single docx, and just hopes for the best. Images and hyperlinks should be ok. But numbering will continue, as will footnotes/endnotes.
      Parameters:
      input -
      data -
      Returns:
      Throws:
      Docx4JException

    • getConsolidatedResultCrude

      public static WordprocessingMLPackage getConsolidatedResultCrude(WordprocessingMLPackage input, List<Map<DataFieldName,String>> data, boolean processHeadersAndFooters) throws Docx4JException
      A "poor man's" approach, which generates the mail merge results as a single docx, and just hopes for the best. Images and hyperlinks should be ok. But numbering will continue, as will footnotes/endnotes. [Advert:] If this isn't working for you, the commercial Enterprise Edition of docx4j (MergeDocx component) will solve your problems.
      Parameters:
      input -
      data -
      processHeadersAndFooters - process headers and footers in FIRST section only. If you have multiple sections in your input docx, performMerge is a better approach
      Returns:
      Throws:
      Docx4JException

    • performMerge

      public static void performMerge(WordprocessingMLPackage input, Map<DataFieldName,String> data, boolean processHeadersAndFooters) throws Docx4JException
      Perform merge on a single instance. This is the best approach, if your input has headers/footers in multiple sections. If you are using MergeDocx, you can use that to join the instances into a single docx. WARNING: The input docx will be modified, so input a copy if that is a problem. This is left to the user, since that can potentially be more efficient, than doing it here.
      Parameters:
      input -
      data -
      processHeadersAndFooters -
      Throws:
      Docx4JException

    • canonicaliseStarts

      protected static void canonicaliseStarts(ComplexFieldLocator fl, List<FieldRef> fieldRefs) throws Docx4JException
      Parameters:
      fl -
      fieldRefs -
      Throws:
      Docx4JException

    • getDatafieldNameFromInstr

      protected static String getDatafieldNameFromInstr(String instr)
      Get the datafield name from, for example <w:instrText xml:space="preserve"> MERGEFIELD Kundenstrasse \* MERGEFORMAT </w:instrText> or <w:instrText xml:space="preserve"> MERGEFIELD Kundenstrasse</w:instrText>

    • extractInstr

      protected static String extractInstr(List<Object> instructions)

    • removeSimpleField

      protected static void removeSimpleField(FieldRef fr)
      Remove the field but preserve the paragraph and content around it
      Parameters:
      fr -

    • getTextInsideContent

      protected static String getTextInsideContent(ContentAccessor paragraph)
      Parse through all content inside the paragraph to concatenate all values inside a text
      Parameters:
      paragraph - The paragraph which contains (or not) data
      Returns:
      All text inside the paragraph

    • recursiveRemove

      protected static void recursiveRemove(ContentAccessor content, Object needToBeRemoved)
      To remove an object from the docx template
      Parameters:
      content - Body (or other part) of the template
      needToBeRemoved - The object that will be removed from the content

    • setMERGEFIELDInOutput

      public static void setMERGEFIELDInOutput(MailMerger.OutputField fieldFate)
      What to do with the MERGEFIELD in the output docx. Default is REMOVED. KEEP_MERGEFIELD will allow you to perform another merge on the output document. The AS_FORMTEXT options convert the MERGEFIELD to a FORMTEXT field. This is convenient if you want users to be able to edit the field, where editing is restricted to forms.
      Parameters:
      fieldFate -

    • setFormFieldProperties

      protected static void setFormFieldProperties(FieldRef fr, String ffName, String ffTextInputFormat)
