Java 如何在CDATA部分处理XML？

我有以下XML部分：

<additionalChargeAttrs><![CDATA[
    <CPEChargeAttrs>
         <complexattributeinfo name =  "Total charge amount" value = "99.00000000"/>
         <complexattributeinfo name =  "Minimum number of installments" value = "3"/>  
         <complexattributeinfo name =  "Maximum number of installments" value = "3"/>  
         <complexattributeinfo name =  "Installment number" value = "1"/>
         <complexattributeinfo name =  "Prorated from date" value = "1960-01-01 19:50:00"/>
         <complexattributeinfo name =  "Prorated to date" value = "2020-12-31 19:50:00"/>
         <complexattributeinfo name =  "Bundle code" value = " "/>
         <complexattributeinfo name =  "Offer subtype" value = "P"/>
         <complexattributeinfo name =  "Installment eligibility" value = "Y"/>
         <complexattributeinfo name =  "NRC charge type" value = "Regular"/>
    </CPEChargeAttrs>
]]></additionalChargeAttrs>

]]>

我想使用JAVA代码将以下元素（在CDATA部分）的值更改为3：

<complexattributeinfo name =  "Installment number" value = "1"/>

CDATA部分的内容是未解析的，这意味着它只是文本blob。您需要获取该文本blob并再次通过XML解析器运行它，更改属性值，将文档写入一个新字符串，并用这个新字符串替换原始CDATA内容
