Apache Camel: set body with regex pattern in Spring DCL - regex

Question

I try to set String body, having cut from it the piece, with the the regular expression, as follows:
<setBody>
<simple>${body} regex '?(:.xml xsi:type="xsd:string">(.*[\s\S]*?)..xml>)'</simple>
</setBody>
it is compiled normally but started with an error:
org.apache.cxf.interceptor.Fault: javax.xml.transform.TransformerException: com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: Illegal processing instruction target ("xml"); xml (case insensitive) is reserved by the specs.
at [row,col {unknown-source}]: [6,7]
also I rty to do this with
<transform> ... </transform>
and the same error appears while running.
Please provide me the simple way to transform the body String in spring DSL by cutting it.
I want to cut xml data from soap plain request:

Use a splitter with an XPath expression such as:
<split>
<xpath>//Structure/Array/Structure</xpath>
<log message="split: ${body}"/>
</split>
