[ISO/IEC 29500-1 1st Edition]

pPr (Paragraph Properties)

This element specifies a set of paragraph properties which shall be applied to the contents of the parent paragraph after all style/numbering/table properties have been applied to the text. These properties are defined as direct formatting, since they are directly applied to the paragraph and supersede any formatting from styles.

[Example: Consider a paragraph which should have a set of paragraph formatting properties. This set of properties is specified in the paragraph properties as follows:

<w:p>
  <w:pPr>
    <w:pBdr>
      <w:bottom w:val="single" w:sz="8" w:space="4" w:color="4F81BD" /> 
    </w:pBdr>
    <w:spacing w:after="300" /> 
    <w:contextualSpacing /> 
  </w:pPr>
</w:p>

The pPr element specifies the properties which are applied to the current paragraph - in this case, a bottom paragraph border using the bottom element (§17.3.1.7), spacing after the paragraph using the spacing element (§17.3.1.33), and that spacing should be ignored for paragraphs above/below of the same style using the contextualSpacing element (§17.3.1.9). end example]

The following example opens an existing word processing document, searches it for a Heading1 styled paragraph, and inserts an outline descendant before that paragraph.

using System.Collections.Generic;

using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Wordprocessing;

namespace ParagraphPropertiesEx

        static void Main(string[] args)
        {
            string fileName = @"C:\Users\Public\Documents\ParagraphPropertiesEx.docx";
            using (WordprocessingDocument wordprocessingDocument = 
                WordprocessingDocument.Open(fileName, true))

                // Get the body element.
                var body = wordprocessingDocument.MainDocumentPart.Document.Body;

                //Define a list to store outline Paragraphs
                var paragraphs = new List<Paragraph>();
