Is there anyone could help me?

Please look at the below description from help.sap.com. You can use the below steps to name the file from a value in the payload. You would have to use File Content Conversion to insert the value of the <text_content> in the file.
Variable Substitution (Target Directory/File Name Scheme)
If you set the Enable indicator, you can enter variables for the Target Directory and File Name Scheme. Enter the names of the variables and references in the table.
●      Enter each variable that you reference in the Target Directory and File Name Scheme fields without the surrounding percentage sign under Name of Variables in the table.
The variables can refer to attributes of the message header or elements of the message payload.
○       If the variables are to refer to an attribute of the message header, add the prefix message: to the name of the variable under Reference. You can specify the following attributes of the message header:
sender_party, sender_service, receiver_party, receiver_service, interface_name, interface_namespace,
message_id (message ID with hyphens, for example 9fbe1ff1-9a0d-11d9-8665-cbf10a126331)
message_id_hex (message ID in hexadecimal format, for example 9fbe1ff19a0d11d98665cbf10a126331)
For example, if you want to specify the interface name from the message header in the target directory or in the file name scheme, enter message:interface_name as the reference.
If one of the message attributes contains characters that are not permitted in a file name, for example \, /, :, *, ?, ", <, >, |, then these characters are replaced by an underscore ("_").
○       If the variable refers to an element in XML schema, add the prefix payload: to the information under Reference. The reference then comprises a pseudo path description in the form of a comma-separated list with the schema namea,na,nameb,nb,....
namea,nameb,...corresponds to the element name and na,nb,... corresponds to the occurrence of the element name at the respective level in the document.
The description begins at the root of the document and ends at the respective element.
To reference the element that is in bold in the example, the following expression is used: payload:root,1,e1,1,e2,2
The parser searches for the first occurrence of the root element at the first level. It then searches for the first occurrence of e1 at the second level and for the second occurrence of e2 at the third level. The content of the last element (u201CExample Valueu201D) is set as the value for a specified variable.
<?xml version="1.0" encoding="UTF-8" ?>
<root>
  <dummy>
     <e1>
        <e2>Data_1</e2>
        <f/>
        <g attr="abc">text</g>
        <e2>Data_2</e2>
     </e1>
  </dummy>
  <e1>
     <e2>illegal/value</e2>
     <f/>
     <g attr="abc">text</g>
     <e2 attr="fghij">Example Value</e2>
  </e1>
</root>
