hello,

i have attached xml and xslt file. Some of the fields are empty in XML file. i have xslt sheet which is retrieving all the data and displaying it. but as some of the fields are empty its printing blank lines. i want to get rid of those blank lines.

when i tried to display with IE it works fine with no blank lines but when i use netscape its giving me blank lines in between.

can anyone tell me how to remove those blank lines?

thanks in advance.

Probably the reason you?re seeing different results in IE and Netscape is that you?re not generating valid HTML. But you probably don?t want a lecture on web standards, you want to know how to only generate output for non-empty elements. Try something like this:

<?xml version="1.0" encoding="ISO-8859-1"?>

<xsl:stylesheet version=“1.0”
xmlns:xsl=“XSLT Namespace”>
<xsl:template match=“calendar”>




<xsl:value-of select=“start_date_string”/>


<xsl:for-each select=“event”>






xsl:apply-templates/

</xsl:for-each>




</xsl:template>

<xsl:template match=“start_time”>
<xsl:value-of select=“.”/> - <xsl:value-of select=“…/end_time”/>
</xsl:template>
<xsl:template match=“end_time”></xsl:template>

<xsl:template match=“e_type|subtitle|spkr_name|spkr_affl|add_speak_title
|add_speak_info|add3_speak_title|add3_speak_info
|other_speak_info|room_name|reception|comments|audience”>
<xsl:if test=“./text()”>
<xsl:value-of select=“.”/>
</xsl:if>
</xsl:template>

<xsl:template match=“title|contact”>
<xsl:value-of select=“.”/>
</xsl:template>
</xsl:stylesheet>


If your source XML document completely left out the unused elements, instead of including them as empty elements, you could leave out the xsl:if element in the next to last template.

Hi

probably Netscape is even working correctly. You may replace e.g.
<xsl:value-of select=“add_speak_title”/>
by
<xsl:if test=“add_speak_title != ‘’”>
<xsl:value-of select=“add_speak_title”/>
</xsl:if>
in order to avoid generation of an empty .

Cheers

PS:
probably you should generate something like … instead of ….
