Re: Converting xml to csv

text nodes in the stylesheet  are only stripped if tehy are -all_ white_
you have

<xsl:template match="power">
	[
	<xsl:value-of select="."/>
	]
<xsl:template>

so your first text node is 
newline,tab,bracket,newline,tab
so that whole text node is copied to the result.

Basic rule is always put literal text in xsl:text so that stylesheet
indentation is then in white space text nodes and will be ignored

<xsl:template match="power">
	<xsl:text>[</xsl:text>
	<xsl:value-of select="."/>
	<xsl:text>]</xsl:text>
<xsl:template>

if you don't want to follow that rule, just make sure that the text
nodes don't have extra whitesoace:

<xsl:template match="power">[<xsl:value-of select="."/>]<xsl:template>
