我有这个

$content = "loose text{{comments}} = {{yolo}}{{comments}} = {{yolo2}}{{comment}} = {{yolo3}}{{comment}} = {{yolo4}}loose text2";

，我想逃脱括号。我在某处读到要逃脱它，请将它们加倍，但即使那样也无法正常工作。

我明白了

Cannot convert value "loose text{{comments}} = {{yolo}}{{comments}} = {{yolo2}}{{comment}} = {{yolo3}}{{comment}} = {{yolo4}}loose text2" to type "system.xml.XmlDocument". Error: "The specified node cannot be inserted as the valid child of this node,because the specified node is the wrong type."
