I have this part of a XML from pubmed:

```
<Abstract>

<AbstractText Label="BACKGROUND" NlmCategory="BACKGROUND"> one </AbstractText> 

<AbstractText Label="METHODS" NlmCategory="METHODS"> two </AbstractText>  

<AbstractText Label="RESULTS" NlmCategory="RESULTS"> three </AbstractText> 

<AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS"> four</AbstractText>  

</Abstract>

```

Depending on the article there is different number labels (range 0-4). The result of the transformation shall be:

**one, two, three, four**

I used this XSL:

```
<COL>
<DATA>
<xsl:value-of select="abstract" />
</DATA>
</COL>

```

Unfortunately this only works if there are no labels and the abstract is provided directly under "abstract" . How do I have to modify this exerpt of the XSL to make it transfer everything that's mentioned under "abstract"? 

Cheers
