[NiFi] Combine FlowFile Attribute and Content

harindar — Fri, 14 Oct 2016 15:51:42 GMT

Im trying to create a xml structure which is required by an external application. The format that they require would be something like this

<root>

<flowfile-content></flowfile-content>

</root>

Im able to get the appropriate structure and the required attributes(passed as Parameters) using TransformXML processor.

However im not sure how to access complete flowfile-content (which is a binary) and append into the structure(inside flowfile-content tag).

@Harry

You should be able to simply use two ReplaceText processors in series to create the XML structure you are looking for:

First replace text configured to prepend text to the binary content as follows:

and the second to append text to the resulting content from the above:

*** Note: if you hold shift key while hitting enter, you will create a new line in the text editor as shown in the above examples. An example of the output from the above would look like this:

There you have the binary content between <flowfile-content> and </flowfile-content>

Now all you need to do is adjust the specific prepend and append values you need.

Thanks,

Matt

That certainly worked! Thank you so much.

One additional question related to this, is there any other way for me to access the flowfile-content within the XSLT file which i would use through Transform XML?
