在 BPEL 中分配字符串列表
有没有办法将输入变量中的字符串列表分配给调用输入变量?问题是我的 Web 服务中有多个输入,因此我无法将输入变量中的包装元素复制到调用变量中的包装变量。将在此处复制代码片段:
<assign name="Assign1">
<copy>
<from variable="inputVariable" part="payload"
query="/ns2:process/ns2:dsaName"/>
<to variable="Invoke1_processList_InputVariable"
part="parameters" query="/ns1:processList/dsaName"/>
</copy>
<copy>
<from variable="inputVariable" part="payload"
query="/ns2:process/ns2:linesOfData"/>
<to variable="Invoke1_processList_InputVariable"
part="parameters" query="/ns1:processList/linesOfData"/>
</copy>
<copy>
<from variable="inputVariable" part="payload"
query="/ns2:process/ns2:description"/>
<to variable="Invoke1_processList_InputVariable"
part="parameters" query="/ns1:processList/description"/>
</copy>
<copy>
<from variable="inputVariable" part="payload"
query="/ns2:process/ns2:application"/>
<to variable="Invoke1_processList_InputVariable"
part="parameters" query="/ns1:processList/application"/>
</copy>
</assign>
问题是只有一个是列表类型,所有其他都是字符串类型。该 XML 是:
<element name="process">
<complexType>
<sequence>
<element name="dsaName" type="string" minOccurs="0"/>
<element name="linesOfData" type="string" minOccurs="0" maxOccurs="unbounded"/>
<element name="description" type="string" minOccurs="0"/>
</sequence>
</complexType>
</element>
<element name="processResponse">
<complexType>
<sequence>
<element name="result" type="string" minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
</schema>
Is there a way to assign a list of strings from input variable to invoke input variable?The problem is that there are multiple inputs in my web service so i am not able to copy the wrapping element in input variable to wrapping variable in invoke variable.Will copy the snippet of the code here :
<assign name="Assign1">
<copy>
<from variable="inputVariable" part="payload"
query="/ns2:process/ns2:dsaName"/>
<to variable="Invoke1_processList_InputVariable"
part="parameters" query="/ns1:processList/dsaName"/>
</copy>
<copy>
<from variable="inputVariable" part="payload"
query="/ns2:process/ns2:linesOfData"/>
<to variable="Invoke1_processList_InputVariable"
part="parameters" query="/ns1:processList/linesOfData"/>
</copy>
<copy>
<from variable="inputVariable" part="payload"
query="/ns2:process/ns2:description"/>
<to variable="Invoke1_processList_InputVariable"
part="parameters" query="/ns1:processList/description"/>
</copy>
<copy>
<from variable="inputVariable" part="payload"
query="/ns2:process/ns2:application"/>
<to variable="Invoke1_processList_InputVariable"
part="parameters" query="/ns1:processList/application"/>
</copy>
</assign>
The problem is that only one is of list type all others are of string type.The XML for this is:
<element name="process">
<complexType>
<sequence>
<element name="dsaName" type="string" minOccurs="0"/>
<element name="linesOfData" type="string" minOccurs="0" maxOccurs="unbounded"/>
<element name="description" type="string" minOccurs="0"/>
</sequence>
</complexType>
</element>
<element name="processResponse">
<complexType>
<sequence>
<element name="result" type="string" minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
</schema>

查看您的架构,您可以使用
doXSLTransform
操作,其中
用于读取列表类型(此处为linesOfData) 并将每个元素添加到
Invoke1_processList_InputVariable
中。Looking at your schema, you can use
doXSLTransform
operation where<xsl:for-each>
is used to read the list type (here it'slinesOfData
) and add each of those elements toInvoke1_processList_InputVariable
.
