Change attribute value of empty tags

[jammer1221]

Hi all,

I'm fairly new to XSL/T and I've been trying to get this problem to work. Here's the set up. I have a document full of MT elements. They contain a N attribute and a V attribute. The N's always have values but the V's sometimes don't. Is it possible to match all empty V attributes and if empty re-write the value for the N attribute?

I've been trying to do it like this:

<xsl:template match="@V[. = '']">
  <xsl:attribute name="N">some new format</xsl:attribute>
</xsl:template>

But, to no avail. Is this sort of thing even possible? Where did I go wrong? Let me know if you need more information!

Thanks,

Matt

You can devise a template for that purpose in conjunction with the other templates you have.
[tt]
<xsl:template match="//MT[@V='']/@N">
<xsl:attribute name="{name()}">
<xsl:value-of select="'some new format'" />
</xsl:attribute>
</xsl:template>
[/tt]

tsuji,

Thanks for the reply and I'm glad you posted that example because it means I haven't been entirely off. Well, I've tried your example (as well as many variations!) and it's not working. So, I'm posting a minimized version of my code in the hopes that you can visually spot an error.

XML:

<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<GSP>
  <RES SN="1" EN="7">
    <R N="1">
      <MT N="VLV-title" V="Title 1"/>
      <MT N="VLV-phone" V="(702) 293-xxxx"/>
    </R>
    <R N="2" L="2">
      <MT N="VLV-title" V="Title 2"/>
      <MT N="VLV-phone" V="(702) 385-xxxx"/>
    </R>
    <R N="3">
      <MT N="VLV-title" V="Title 3"/>
      <MT N="VLV-phone" V="(702) 785-xxxx"/>
      <MT N="VLV-fax" V="(702) 785-xxxx"/>
    </R>
    <R N="4">
      <MT N="VLV-title" V="Title 4"/>
      <MT N="VLV-phone" V="(702) 456-xxxx"/>
      <MT N="VLV-fax" V=""/>
    </R>
    <R N="5">
      <MT N="VLV-title" V="Title 5"/>
      <MT N="VLV-phone" V="(702) 456-xxxx"/>
      <MT N="VLV-fax" V="(702) 456-xxxx"/>
    </R>
  </RES>
</GSP>

XSL:

<xsl:stylesheet xmlns:xsl="[URL unfurl="true"]http://www.w3.org/1999/XSL/Transform"[/URL] version="2.0">
<xsl:output method="html" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" omit-xml-declaration="yes" />
<xsl:template match="//MT[@V='']/@N">
    <xsl:attribute name="V">s</xsl:attribute>
</xsl:template>

<xsl:template match="GSP">
	<xsl:for-each select="RES">
		<xsl:for-each select="R">
    	<div>
        	<div style="float:left;">
			<xsl:apply-templates select="MT[@N='VLV-title']"/>
            </div>
            <div style="float:right">
            <xsl:apply-templates select="MT[@N='VLV-phone']"/>
            <xsl:if test="MT[@N='VLV-phone'] and MT[@N='VLV-fax']"> | </xsl:if>
            <xsl:apply-templates select="MT[@N='VLV-fax']"/>
            </div>
        </div><br />

		</xsl:for-each>
	</xsl:for-each>
</xsl:template>
<xsl:template match="MT">
	<xsl:if test="@V!='' and contains(@V,'null')=false">
	    <xsl:value-of select="@V" disable-output-escaping="yes"/>
    </xsl:if>
</xsl:template>   
</xsl:stylesheet>

Expected Results:

Title 1
(702) 293-xxxx

Title 2
(702) 385-xxxx

Title 3
(702) 785-xxxx | (702) 785-xxxx

Title 4 
(702) 456-xxxx

Title 5
(702) 456-xxxx | (702) 456-xxxx

As you can tell, I'm outputting the value and then in the next line checking if an adjacent MT element is there; if so, then ouput a pipe and then the value. If not, then no pipe.

Thanks again for your help! It is much appreciated!

Matt

That sure would be a different question than what I would reasonably deduce form the original post. Try this.
[tt]
<xsl:stylesheet xmlns:xsl="[ignore]

http://www.w3.org/1999/XSL/Transform

[/ignore]" version="2.0">
<xslutput method="html" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" omit-xml-declaration="yes" />

<xsl:template match="GSP">
<xsl:for-each select="RES">
<xsl:for-each select="R">
<xsl:apply-templates select="MT[@N='VLV-title']"/>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
<xsl:template match="MT[@N='VLV-title']">
<div style="float:left;">
<xsl:value-of select="@V" />
</div>
<div style="float:right">
<xsl:for-each select="following-sibling::MT[@V!='']">
<xsl:value-of select="@V" />
<xsl:if test="following-sibling::MT[@V!='']">
<xsl:value-of select="' | '" />
</xsl:if>
</xsl:for-each>
</div>
<br />
</xsl:template>
</xsl:stylesheet>
[/tt]

tsuji,

That code works great for that specific example, but, the XML I posted was a simplified version. In case you feel like a challenge this early in the morning...

I can post the XLST I have this far too...

Thanks a ton!

Just modify the specific template.
[tt]
<xsl:template match="MT[@N='VLV-title']">
<div style="float:left;">
<xsl:value-of select="@V" />
</div>
<div style="float:right">
<xsl:for-each select="following-sibling::MT[@V!=''][@N='VLV-phone' or @N='VLV-fax']">
<xsl:value-of select="@V" />
<xsl:if test="following-sibling::MT[@V!=''][@N='VLV-phone' or @N='VLV-fax']">
<xsl:value-of select="' | '" />
</xsl:if>
</xsl:for-each>
</div>
<br />
</xsl:template>
[/tt]
