# Pass XML Attributes

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

DataWeave enables you to pass attributes from within an XML tag input source to the target output
XML. The DataWeave example shows how to pass the XML attributes in the `NameDetail` field of the
input source payload to the `TargetName` field of the XML output.

This example uses: - `.*` multivalue selector that returns an array of `NameDetail` elements. -
`map` function to iterate over the array of NameDetail elements of the input. - The dynamic
attribute expression `@dynamicAttributes` to create the attributes of the new output tag by
selecting the attributes dynamically from the input.

DataWeave Script:

```dataweave
%dw 2.0
output application/xml
---
{
    Result: {
        (payload.Names.*NameDetail  map ( nameDetail , indexOfNameDetail ) -> {
            TargetName @((nameDetail.@)): {
                item: nameDetail.item
            }
        })
    }
}
```

Input XML Payload:

```xml
<?xml version="1.0" encoding="UTF-8"?>
      <Names>
         <NameDetail NameId="11111" NameType="Person" Name="Richarson" GivenNames="John" PreferredLanguage="English" CompanyNumber="" Gender="Male" Title="" >
            <item>doo</item>
         </NameDetail>
         <NameDetail NameId="22222" NameType="Person" Name="Richarson" GivenNames="Susan" PreferredLanguage="Spanish" CompanyNumber="" Gender="Female" Title="" >
            <item>dah</item>
         </NameDetail>
         <NameDetail NameId="33333" NameType="Person" Name="Knox" GivenNames="Frances" PreferredLanguage="English" CompanyNumber="" Gender="Male" Title="" >
            <item>dab</item>
         </NameDetail>
      </Names>
```

Output XML:

```xml
<?xml version='1.0' encoding='UTF-8'?>
<Result>
  <TargetName NameId="11111" NameType="Person" Name="Richarson" GivenNames="John" PreferredLanguage="English" CompanyNumber="" Gender="Male" Title="">
    <item>doo</item>
  </TargetName>
  <TargetName NameId="22222" NameType="Person" Name="Richarson" GivenNames="Susan" PreferredLanguage="Spanish" CompanyNumber="" Gender="Female" Title="">
    <item>dah</item>
  </TargetName>
  <TargetName NameId="33333" NameType="Person" Name="Knox" GivenNames="Frances" PreferredLanguage="English" CompanyNumber="" Gender="Male" Title="">
    <item>dab</item>
  </TargetName>
</Result>
```
