xml - Simple XSLT where the IF test is failing -

i have simple xml document i'm trying replace element based on element's value.

<document> <meta>     <wk_abc>         ucm:source1     </wk_abc>     <wk_def>         other text     </wk_def>     <wk_abc>         ucm:source2     </wk_abc> </meta> <content>     lorem ipsum </content> </document> 

my xsl this:

<xsl:template match="@* | node()">     <xsl:copy>         <xsl:apply-templates select="@* | node()" />     </xsl:copy> </xsl:template>  <xsl:template match="wk_abc">    <xsl:if test=".='ucm:source1'">         <bob>bob</bob>     </xsl:if> </xsl:template> 

but keeps failing if condition. , skipping on replacement element. why test failing?

this because there whitespace either side of 'ucm:source1' in node.

try changing xsl:if condition remove white-space before doing check:

  <xsl:if test="normalize-space()='ucm:source1'"> 

note more trim white space. if text ucm:source1 ucmsource2 example, whitepsaces in middle merged 1 single space, normalize-space return ucm:source1 ucmsource2
