Xml xslt question
I have an xml that has text inside "word" elements like
<word>Police</word>
<word>confirmed</word>
<word>they are</word>
<word>questioning</word>
<word>a</word>
<word>man</word>
The problem is when I apply xslt the text appears as "Policeconfirmedthey arequestioningaman".
Here is an xslt snippet that does this conversion
<Paragraph>
<xsl:for-each select="./speaker/segment">
<xsl:value-of select="./nbest"/>
</xsl:for-each>
</Paragraph>
Can anyone offer any help as to how I can show this as "The police have confirmed they are interrogating the person"?
Many thanks.

Add a whitespace character.
Simple way:
<Paragraph>
<xsl:for-each select="./speaker/segment">
<xsl:value-of select="./nbest"/> 
</xsl:for-each>
</Paragraph>
A slightly more complex way to effectively trim a string:
<Paragraph>
<xsl:for-each select="./speaker/segment">
<xsl:if test="not(position() = 1)"> </xsl:if>
<xsl:value-of select="./nbest"/>
</xsl:for-each>
</Paragraph>
And some xpath ways: normalize-space , substring before , substring after in various forms.

You can conditionally add space between words based on word position. The following snippet shows how to add a space after everything but the last word.
<xsl:template match="//words">
<xsl:for-each select="word">
<xsl:value-of select="."/>
<!-- Check word position -->
<xsl:if test="position()!=last()">
<!-- Add a whitespace if it not the last word -->
<xsl:text> </xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:template>
If you are generating HTML output, you can use the information from this post to see how to add a space (instead of <xst: text> in my code snippet)

it's almost like the answer "aku". But answering "aku" creates one paragraph.
<xsl:for-each select="./speaker/segment">
<Paragraph>
<xsl:for-each select="./nbest/word"/>
<xsl:value-of select="."/>
<xsl:if test="position()!=last()">
<xsl:text> </xsl:text>
</xsl:if>
</xsl:for-each>
</Paragraph>
</xsl:for-each>

The reason they work together is because the stylesheet uses a built-in pattern to match against which whitespace collapses. I don't see where you are explicitly calling <word/>
or the surrounding XML, so I am assuming this is calling <xsl:apply-templates />
somewhere. You just need to just define the match pattern as such:
<xsl:template match="word">
<xsl:value-of select="." /> 
</xsl:template>
The whitespace is significant, so if you find in the above solution that it confuses everything, you can wrap it inside the <xsl:text/>
node and the whitespace will disappear.
Then when the word node is matched you get it from a distance. Note: there will be extra space at the end. To get rid of this, it will be slightly longer.
<xsl:temmplate match="word">
<xsl:value-of select="." />
<xsl:if test=". !=../word[last()]">
<xsl:text> </xsl:text>
</xsl:if>
</xsl:template>
This will only work when applying templates, not when using values or copies of xsl directives.
