Create a attribute dynamically - xslt

Question

I'm writing an xsl script in which I need to create the attribute dynamically.
Here is my sample code.
<Table BORDERLINESTYLE="solid" BOTTOMMARGIN="12" NOTEGROUPSPACING="single" CELLPADDING="0" CELLSPACING="0" WIDTH="504"></Table>
Here BORDERLINESTYLE may or may not be available to all Table tags. and I want the output to be something like this.
<table style="border-style:solid; border-margin:12px; width:504px"></table>
Here are 2 things that I've tried.
1. Creating attributes
<table>
<xsl:if test="./#BORDERLINESTYLE">
<xsl:attribute name="border" select="'1px solid'"/>
</xsl:if>
<xsl:if test="./#WIDTH">
<xsl:attribute name="width" select="concat(./#WIDTH, 'px')"/>
</xsl:if>
<xsl:if test="./#BOTTOMMARGIN">
<xsl:attribute name="border" select="'1px solid'"/>
</xsl:if>
<xsl:apply-templates/>
</table>
the output that I get is as below.
<table border="1px solid" width="504px">
2. Inline adding
<table style="width:{current()/#WIDTH,'px'}; border:{./#BORDERLINESTYLE}; margin-bottom: {./#BOTTOMMARGIN, 'px'}; margin-top:{./#TOPMARGIN, 'px'}; "></table>
and the output is as below with some blank values like margin-top
<table style="width:504 px; border:solid; margin-bottom: 12 px; margin-top:px; ">
How can I add styles to style based on the attributes provided in the XML?
I'm using XSLT2.0.

Answer 1

I would use something like this:
<xsl:if test="#BORDERLINESTYLE|#WIDTH|#BOTTOMMARGIN|#TOPMARGIN">
<xsl:attribute name="style">
<xsl:if test="#BORDERLINESTYLE">
<xsl:text>border:1px solid;</xsl:text>
</xsl:if>
<xsl:if test="#WIDTH">
<xsl:value-of select="concat('width:',#WIDTH, 'px;')"/>
</xsl:if>
<xsl:if test="#BOTTOMMARGIN">
<xsl:value-of select="concat('margin-bottom:',#BOTTOMMARGIN, 'px;')"/>
</xsl:if>
<xsl:if test="#TOPMARGIN">
<xsl:value-of select="concat('margin-top:',#TOPMARGIN, 'px;')"/>
</xsl:if>
</xsl:attribute>
</xsl:if>
And depending on the business rules for mapping those source-attributes to style attributes change the code accordingly.
Btw.: ./# is the same as #

Answer 2

Use if else Function
For Example
margin-top: {if(//#TOPMARGIN!=0) then {./#TOPMARGIN, 'px'} else '12px'}

I need to create the attribute dynamically.
Actually, you want to populate the attribute dynamically - which could be done by applying a template to each input attribute you want to use:
<xsl:template match="Table">
<table>
<xsl:attribute name="style">
<xsl:apply-templates select="#BORDERLINESTYLE | #BOTTOMMARGIN | #WIDTH"/>
</xsl:attribute>
</table>
</xsl:template>
<xsl:template match="#BORDERLINESTYLE">
<xsl:text>border-style:</xsl:text>
<xsl:value-of select="."/>
<xsl:text>; </xsl:text>
</xsl:template>
<xsl:template match="#BOTTOMMARGIN">
<xsl:text>border-margin:</xsl:text>
<xsl:value-of select="."/>
<xsl:text>px; </xsl:text>
</xsl:template>
<xsl:template match="#WIDTH">
<xsl:text>width:</xsl:text>
<xsl:value-of select="."/>
<xsl:text>; </xsl:text>
</xsl:template>
