来自PHP DOM的单元格中的Excel XML换行符

我正在尝试在Excel XML文档中插入新行.我需要插入的实体是
 ，但是每当我将其插入PHP DOM时，它只会将其转换为正常的换行符.

I am trying to insert new lines into an Excel XML document. The entity that I need to insert is 
 but whenever I insert that into PHP DOM, it just converts it to a normal line break.

这就是我得到的:

<Cell><Data>text
text2
</Data></Cell>

这就是我想要的:

<Cell><Data>text&#10;text2&#10;</Data></Cell>

我无法弄清楚如何插入新行并以这种方式对其进行编码，或者添加没有该字符的字符，要么对其进行双重编码，要么将其转换为新行.

I cannot figure out how to insert a new line and get it to encode that way, or add that character without it either double encoding it, or converting it to a new line.

感谢您的帮助！
