wso2esb 中是否有任何 replace 类型的函数?

is there any replace kind of function in wso2esb?

推荐答案

replace 是 XPath 2.0 附带的一个函数.要启用 XPath 2.0 功能，请取消注释位于 $ESB_HOME/repository/conf 目录下的 synapse.properties 文件中的以下条目.

replace is a function that comes with XPath 2.0. To enable XPath 2.0 functions uncomment the following entry in the synapse.properties file which is located at $ESB_HOME/repository/conf directory.

synapse.xpath.dom.failover.enabled=true

那么你必须如下指定中介者，

then you have to specify the mediator as follows,

<property
expression="fn:replace('your_original_string', 'pattern_to_replace', 'your_new_string')"
name="NEWSTRING" scope="default" type="STRING"
xmlns:fn="http://www.w3.org/2005/xpath-functions" />
