As someone (David C?) said,

ONLY white space nodes are removed from the stylesheet. If a node contains something apart from whitespace, it is not removed (and the whitespace it contains is not removed either).

So if you have

[...]<xsl:for-each select="centers/center">
         "<xsl:value-of [...]

That really means "output a text node containing a newline character followed by some spaces and then a " sign.

Hi,
I have yet another problem sorting out the whitespace issue(i do not know if i can really call it as a whitespace issue )
The problem is as follows...
i want the ids to appear one below the other between the quots like.


"3100004"
"3100007"
"80000"
"3100012"
"3000900"
"80001"
So I write the XSL code as below
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet SYSTEM "D:\xsl-exp\characterEntities\entityref.dtd">
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text" omit-xml-declaration="yes"/>
<xsl:template match="/">
<!--line 1 --> <xsl:for-each select="centers/center"> "<xsl:value-of select=" @id"/>"
<xsl:text>&#xa;</xsl:text>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>


In the above code , where line 1 is,
1.If i write the "<xsl:value-of select=" @id"/>"
below the for loop ( in the next line of the for-each)
i get the results as ( note the spaces before the id and the extra newline after each ID
<----Spaces----


"3100004"
"3100007"


"80000"

"3100012"

"3000900"

"80001"
2. If i write "<xsl:value-of select=" @id"/>" in the same line as the for-each and <xsl:text>&#xa;</xsl:text> in the next line,
then i get result as( note that the spaces before id is sorted but there is an extra newline )


"3100004"
		
"3100007"
		
"80000"
		
"3100012"
		
"3000900"
		
"80001"

3. If however i write the "<xsl:value-of select=" @id"/>" and <xsl:text>&#xa;</xsl:text> in the same line as xsl:for-each , i get the result what i wanted.. eg., if xsl code is <xsl:for-each select="schedule/timeslot">"<xsl:value-of select="@id"/>"<xsl:text>&#xa;</xsl:text> ( in the same line)
Then the result is as desired.. like below( note that there are no spaces and no extra newlines)


"3100004"
"3100007"
"80000"
"3100012"
"3000900"
"80001"

I am not really sure how the XSLT processor outputs the space.I am really concerned because output is depending upon the XSL structure..if i use the tidy option in xselerator, then it arrainges the loops etc in a proper indented way, which will then not get what i want. I am concerned as to how the structure of the XSL coding can impact the output?? is there any way to get around this?
Thanks Very Much
Subbu
