Is there any way to make it faster...bcoz its taking too long (for a 1.25 MB xml file taking forever). I do understand that for each n every node() it's looking for template match but is there any better.faster way to do it.

Thanks,
Trishla

Can you show the XSLT you ended up using, I don't see why it should take that long? How many book elements are in the real XML?

The book structure is just a simlified example to show what I'm doing but anyway it has around 2500-3000 <ook>and many more element inside <book>node, which I purposely did not put here.

Also, I'm doing some more trimming of spaces apart from what I stated as condition here like removing whitespace node with <xsl:strip-space elements="."> and removing preceding and trailing spaces with normalize-space function.

Here is the stylesheet:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
    <xsl:template match="node()">
        <xsl:copy>
            <xsl:apply-templates/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="node()" mode="strip-all">
        <xsl:copy>
            <xsl:apply-templates mode="strip-all"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="node()" mode="strip-some">
        <xsl:copy>
            <xsl:apply-templates mode="strip-some"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="node()" mode="strip-quad">
        <xsl:copy>
            <xsl:apply-templates mode="strip-quad"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="book[topic='Biology']">
        <xsl:copy>
            <xsl:apply-templates mode="strip-quad"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="text()" mode="strip-quad">
    <xsl:value-of select="normalize-space()"></xsl:value-of>

    </xsl:template>


    <xsl:template match="book[topic='programming'] | book[topic='Computers']">
        <xsl:copy>
            <xsl:apply-templates mode="strip-all"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="text()" mode="strip-all">
    <xsl:strip-space elements="."></xsl:strip-space>
        <xsl:value-of select="translate(normalize-space(.), ' ', '')"/>
    </xsl:template>
    <xsl:template match="book[topic='Literature']">
        <xsl:copy>
            <xsl:apply-templates mode="strip-some"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="text()[not(contains(preceding::text()[1], 'Lang'))]" mode="strip-some">
        <xsl:value-of select="translate(., ' ', '')"/>
    </xsl:template>
</xsl:stylesheet>

Well that looks a bit dodgy, xsl:strip-space elements shouldn't be inside a template. Can you email me the actual books XML? You can send it to joefawcett at hotmail dot com.

I even try to run it without <xsl:strip-element> and it took same time which is over 9 minutes.

Well if you email the books data as I suggested I'll run it on my machine.

I can only surmise that you are using a processor with a very naive implementation of

preceding::text()[1]

Try a different XSLT processor, and it may go 100 times faster.
