通过openxml创建空格，在Word Document中使用AltChunk将文本替换为rtf文件内容

Question

我试图用主Word Document（目标）中的textToReplaceByRTFContent替换rtf文件内容。但是，rtf文件中的内容会插入到目标文件中。但是在目标文件中创建了一个空间。从rtf文件插入的内容的左缩进变为0.56。 我想摆脱空格（左缩进应为0）

我已在以下链接中复制了rtf文件和CriteriaTest.docx文件。 我需要用Test.rtf内容替换CriteriaTest.docx中的“ CRITERIA-1”文本。 以下代码可以很好地解决缩进问题。请帮我摆脱这个问题。
