我正在尝试通过php函数转换xml数据，但遇到了解析器错误 1. 接受存款 RF>LF=已付款 RF大于已付，LF等于已付 10 合并人/特许人/互联网 RF>=LF=LF=LFLF>付费 右前角较大/相等左前角、左前角较低/相等支付 18 不方便的行程 RF>=LF=LF=LF=LF=LF=LF>=LF=LF=LF=LFLF=已付款 RF高付费，LF低付费 28 拒绝合并者票价 RF>=LF=LF=LF=LF低频=LF=LF=LF>付费 已付为0，RF大于/等于LF，LF大于已付 4. 要求商务舱 射频>低频=LF>=LF==LF=LF=LF=LF=LF=LFLF=LF>=LF>=LF>=LF>=LF>=LF>LF=LF=LF=LF>=LF>=LF>=LF>=PAYED 规则>已付为0，RF大于/等于LF，LF大于已付

您的xml上有逻辑运算符，因此运行此操作时会出现xml解析错误。尝试使用CDATA来避免这种情况，例如

=LF

并使用

LIBXML\u NOCDATA

参数将CDATA合并为文本节点

希望这段代码能帮助你
