How to append an OdfTextDocument to another OdfTextDocument

[HelmutL]

Hi,
most probably, I am dumb.
I had done this already using simple.TextDocument, but I want to get rid of it.

But I cannot find out how to do using OdfTextDocuments. Or at least append the content of the second document.

Thanks in advance
Helmut

Hello Helmut, I have not required nor used such an append/merge ODT functionality. When I look at org.odftoolkit.odfdom.doc.OdfTextDocument and its parent org.odftoolkit.odfdom.doc.OdfDocument I can not find such functionality, so it seems it simply does not exist, yet. If this already existed in Simple API, you should try to port it back to ODFDOM. The following functionality comes initially to my mind: 1. Copy the content beyond <office:body> behind the content of the other beyond <office:body> But beware there is also a content-prelude: https://docs.oasis-open.org/office/OpenDocument/v1.3/os/schemas/OpenDocument-v1.3-schema-rng.html#office-text-content-prelude a content-epilogue: https://docs.oasis-open.org/office/OpenDocument/v1.3/os/schemas/OpenDocument-v1.3-schema-rng.html#office-text-content-epilogue which needs to be merged when it exists! 2. As it is a generic functionality for all ODF documents, you might place it at its parent OdfDocument. But you need to override at least parts as the content of <office:body> differs and you will not be able to append different document types: https://docs.oasis-open.org/office/OpenDocument/v1.3/os/schemas/OpenDocument-v1.3-schema-rng.html#office-body-content 3. All used automatic and template styles must be copied as well, if not already existent - or if the same in name but different in formatting properties must be renamed 4. The footer/header of one document will likely win, right? I the styles.xml. 5. How about the data of meta.xml? Depends on the metadata, right? 6. If both documents use the same @xml:id one has to be changed. 7. Directories of embedded documents as files have to be copied into the new zip 8. ...there might be more challenges that will be revealed when starting. Perhaps you take a look at the content.xml of a complex file https://docs.oasis-open.org/office/OpenDocument/v1.3/os/part2-packages/OpenDocument-v1.3-os-part2-packages.odt or even bigger https://docs.oasis-open.org/office/OpenDocument/v1.3/os/part3-schema/OpenDocument-v1.3-os-part3-schema.odt Perhaps starting to port the previous SimpleAPI functionality and explaining its limitations might already help when it suits your needs. :-) Any pull request is very welcome! Godspeed! Svante
