How to prevent Drupal export XML formatter adding paragraphs? I'm exporting nodes as XML and with fields in most nodes set to "Plain text" format. Everything is fine when I'm editing them, but when exporting an extra paragraph (&lt;p&gt;) tag is added around text (using "Default" formatter).

The mentioned field has a variable length text (some are short like "Book" and some have long HTML). Some longer texts are exported fine, but those short ones all have extra paragraph around them (e.g. &lt;p&gt;Book&lt;/p&gt;).

So is there some option I can check to disable adding those paragraphs or even disable any formatting? Or maybe I have to install/make some special module for formatting?

PS: I'm using Views data export (version 7.x-3.0-beta8).
I don't think there is a need to make a "special module". Instead you could install the Forena module (with quite a few official D7 releases ...), as an alternative to what you're trying to do with the Views Data Export module (or the Views Datasource module as suggested in one of the comments to the question here).

You could use the Forena module to create an appropriate report. As per your comment like "Full nodes, no. Only some choosen fields, but all of a single content type." such report should be straight forward to create. And then create an XML file from the report data (= query results). Similar solution for somebody who rather wants/needs a JSON format. Refer to my answer to "How to add a link to the CSV download to my module page, for a report created with Forena?" for more details about all sorts of export formats, and some online demo samples.

Using this alternative, you probably don't need your (not ideal) work-around anymore which is to disable changing new lines to HTML new lines.
