how to apply space between data in xslt - xslt

Question

xml
<block4>
<tag>
<name>50K</name>
<value>
0501/045788775099
Praveen // name will come
MENENDEZ Y PELAYOA CORUNA SPA // address will come
</value>
</tag>
</block4>
i have written a xslt for this above tag but i have facing a problem with replacing remaining length with space
the above value you can see in middle line praveen is there let us assume for this xml message praveen we recieved for another message we cam may be recieve Tom but maximum length is 35 so we need to caluclate the string name value remaining length we should replace with SPACE so i dunno how replace a space over there ...
xsl
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" />
<xsl:template match="/">
<xsl:for-each select ="block4/tag[name = '50K']">
<xsl:value-of select="concat(substring(value, 1, 5), ',',substring(substring- before(value,'
'),6), ',',substring-after(value,'
'))" />
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
EXpected OUPUT lIKE:
0501/,045788775099,praveen............................MENENDEZ Y PELAYOA CORUNA SPA
where dots represents space dont assume dots
i need space over there assume think praveen is 7 char and remaining 28 char should make space wantedly in xslt

Answer 1

Try using
<xsl:text> </xsl:text>
The space is between those tags.

Answer 2

let us assume for this xml message
praveen we recieved for another
message we cam may be recieve Tom but
maximum length is 35 so we need to
caluclate the string name value
remaining length we should replace
with SPACE so i dunno how replace a
space over there ...
Use:
substring(concat($vstr, $vBlanks35), 1, 35)
This evaluates to the result of concatenating $vstr ('Praveen') with $vBlanks35 (35 blanks) and then taking the starting 35 characters.
Here is a complete example:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="vstr" select="'Praveen'"/>
<xsl:variable name="vBlanks35" select=
"' '"/>
<xsl:template match="/">
"<xsl:value-of select=
"substring(concat($vstr, $vBlanks35), 1, 35)"/>"
</xsl:template>
</xsl:stylesheet>
when this transformation is applied on any XML document (not used), the wanted, correct result is produced:
"Praveen "

Answer 3

One (universal) way to add space in xml is to use the special xml attribute that preserves spaces:
<value xml:space="preserve">
your
values
here ...
</value>
Another method is to use XSL's preserve/strip space ...

You should use a XSLT version of SQL function RPAD:
<xsl:template name="rpad">
<xsl:param name="text" />
<xsl:param name="length" />
<xsl:param name="char" select="' '" />
<xsl:if test="$length > 0 and string-length($text) > 0">
<xsl:value-of select="$text" />
<xsl:call-template name="rpad">
<xsl:with-param name="text" select="$char" />
<xsl:with-param name="char" select="$char" />
<xsl:with-param name="length" select="$length - string-length($text)" />
</xsl:call-template>
</xsl:if>
</xsl:template>
Usage:
<xsl:call-template name="rpad">
<xsl:with-param name="text" select="'your string here'" />
<xsl:with-param name="length" select="35" />
</xsl:call-template>
Optionnally you may specify a char parameter for padding your string with a character other than space.
