Inserting newlines in Word using OpenXML

Question

I am using openxml WordProcessingDocument to open a Word template and replace placeholder x1 with a string. This works fine unless I need the string to contain a newline. How can I replace x1 with text may contain newlines that word would recognise? I have tried \n \r but these do not work

Just to explain further when the word template is opened I read it into a StreamReader then use .Replace to replace x1.

Answer 1

To insert newlines, you have to add a Break instance to the Run.

Example:

run.AppendChild(new Text("Hello"));
run.AppendChild(new Break());
run.AppendChild(new Text("world"));

The XML produced will be something like:

<w:r>
  <w:t>Hello</w:t>
  <w:br/>
  <w:t>world</w:t>
</w:r>

Answer 2

Here's a C# function that will take a string, split it on line breaks and render it in OpenXML. To use, instantiate a Run and pass it into the function with a string.

void parseTextForOpenXML( Run run, string textualData )
{
    string[ ] newLineArray = { Environment.NewLine };
    string[ ] textArray = textualData.Split( newLineArray, StringSplitOptions.None );

    bool first = true;

    foreach ( string line in textArray )
    {
        if ( ! first )
        {
            run.Append( new Break( ) );
        }

        first = false;

        Text txt = new Text( );
        txt.Text = line;
        run.Append( txt );
    }

Answer 3

I have the same issue and in my case <w:br /> tag worked.

Answer 4

Altough this question is already answered I have another approach to solve questions like :

How can I make XXX with OpenXML??

In this cases you could make use of the powerful Microsoft OpenXML productivity tool (also known as OpenXmlSdkTool). Download here.

1. Create a new office document
2. Add the parts to the document which you would like to reproduce with OpenXML SDK.
3. Open the office document with Microsoft OpenXML productivity tool
4. Click on "Reflect Code"
5. On the right side you will see now you document reflected into C# code.
