[TYPO3-templavoila] prepend text to content of input-field

[Michael Bakonyi]

Hi,

I've got a input-field here which looks like that:

<field_date type="array">
	<tx_templavoila type="array">
		<title>Datum</title>
		<sample_data type="array">
			<numIndex index="0"></numIndex>
		</sample_data>
		<eType>input</eType>
		<proc type="array">
			<HSC type="integer">1</HSC>
		</proc>
	</tx_templavoila>
	<TCEforms type="array">
		<config type="array">
			<type>input</type>
			<size>48</size>
			<eval>trim</eval>
		</config>
		<label>Datum</label>
	</TCEforms>
</field_date>

Now I'd like to always prepend some Text via stdWrap to this content in 
the frontend. I dont't know if it's possible because there's no 
Typoscript-Section in the DS when using input-fields ..

Would appreciate some help :-)
