Finding and replacing placeholders is divided into several <w: t> -Elements

I am trying to create reports from .docx-Templates using the Open XML SDK 2.5. In the templates, I defined some placeholders that are replaced with real values. Placeholders can be defined in various schemes, such as

<#Name#>
or
<!#Name#!>
or
#Name#
or
{{Name}}

The placeholder layout can also be in a different format if the placeholders can be clearly identified within the text.

The problem I am facing right now is that the placeholder is often split into multiple <w:t>-Elements ( DocumentFormat.OpenXml.Wordprocessing.Text) in <w:p>-Element ( DocumentFormat.OpenXml.Wordprocessing.Paragraph). Example

<w:p w:rsidR="003137E0" w:rsidRDefault="008C62F1" w:rsidP="00D43D55">
  <w:r>
    <w:t xml:space="preserve">#FirstName# </w:t>
  </w:r>
  <w:r w:rsidR="00C93A70">
    <w:t>#LastName</w:t>
  </w:r>
  <w:r w:rsidR="005F49B7">
    <w:t>#</w:t>
  </w:r>
</w:p>

placeholder #FirstName# , <w:t> -Element, placeholder #LastName# <w:t> -Elements, Regex ,

Regex placeholderRegex = new Regex(@"#[\w]*#");

document.MainDocumentPart.Document.Body.Descendants<Text>().Where(t=> placeholderRegex.IsMatch(t.Text))

, , , . , <w:t> -Elements.

, {{[\w]*}} .

(Docx)

{{Ort}}
And this {{placeholder}} is within the text
