there several issues stylesheet prevent being parsed , executed produce desired output.
first, attempts construct <img> elements , construct value @src not work. in xslt not construct xml string, need construct nodes happen serialized xml. instead of:
<xsl:text disable-output-escaping="yes"> <img src="http://us.i1.yimg.com/us.yimg.com/i/us/we/52/ </xsl:text> <xsl:value-of select="@code"/> <xsl:text disable-output-escaping="yes">.gif"/></xsl:text> you should create well-formed img element , use attribute value template construct @src value:
<img src="http://us.i1.yimg.com/us.yimg.com/i/us/we/52/{@code}.gif"/> second, < character in xpath: <xsl:for-each select="(rss/channel/item/yweather:forecast)[position() < 3]"> comparing position of items in for-each needs encoded: <xsl:for-each select="(rss/channel/item/yweather:forecast)[position() < 3]">
finally, in several places using <xsl:copy-of select="$scale"/>, attribute. using in places in attribute cannot copied. believe intended achieve emit value of attribute, should instead use: <xsl:value-of select="$scale"/>.
applying fixes xslt:
