quick xslt for-each question

Question

Let's say I have an XML document that has this:

<keywords>
<keyword>test</keyword>
<keyword>test2</keyword>
<keyword>test3</keyword>
<keyword>test4</keyword>
</keywords>

And i want to use XSLT to print it out in HTML like this:

<ul>
<li>test</li>
<li>test2</li>
<li>test3</li>
<li>test4</li>
</ul>

What would my XSLT look like? I tried this:

<ul>
<xsl:for-each select="keywords/keyword">
    <li><xsl:value-of select="keyword"/></li>
</xsl:for-each>
</ul>

but that doesn't print out the keyword value, just a blank item.

<ul>
<xsl:for-each select="keywords">
    <li><xsl:value-of select="keyword"/></li>
</xsl:for-each>
</ul>

doesn't work (for obvious reasons), but at least it prints the first keyword!

suggestions? thanks!

Answer 1

<ul>
<xsl:for-each select="keywords/keyword">    
  <li><xsl:value-of select="text()"/></li>
</xsl:for-each>
</ul>

using text() should get you the text inside the keyword node

Answer 2

I would suggest avoiding for-each here, and doing it using a template - it's more idiomatic in XSLT, especially when you have a clear one-to-one mapping:

<xsl:template match="keyword">
    <li><xsl:value-of select="."/></li>
</xsl:template>

<xsl:template match="keywords">
    <ul><xsl:apply-templates/></ul>
</xsl:template>
