XSL if test with multiple test conditions

Question

Solved   Thanks to  IanRoberts  I had to use the normalize-space function on my nodes to check if they were empty    lt xsl if test    node ABC      and  normalize-space node DEF      and  normalize-space node GHI        gt    This worked perfectly fine   lt  xsl if gt     Problem   I am trying to create a xsl condition to check if combinations of node are empty or not  I have tried below conditions but they do not work  does anyone have an idea as to how to get it working   lt xsl if test   node ABC     and node DEF    and node GHI      gt  This does not work  lt  xsl if gt    I have also tried   lt xsl when test    node ABC      and  node DEF     and  node GHI       gt  This does not work either    lt  xsl when gt    And also tried   lt xsl if test   node ABC      gt   lt xsl if test   node DEF     gt   lt xsl if test   node GHI      gt  Nope not working    lt  xsl if gt   lt  xsl if gt   lt  xsl if gt    I  then tried with single xsl if conditions  and below is the observation   lt xsl if test  node ABC     gt    This is working fine    lt  xsl if gt    However if i try to search for empty condition  i e   lt xsl if test  node ABC    gt    This does not work    lt  xsl if gt    Also  if i try with a     double equal to   then it gives xslt error  i e   lt xsl if test  node ABC     gt     This gives a compilation error     lt  xsl if gt    I would like help in figuring out how to get my xsl if test working to check for multiple conditions  Thanks in advance    Edit    Just to update here that the if condition where all the nodes are not empty works  it does not work when i try to check for any other node out of the three nodes that are empty   For eg      lt xsl if test   node ABC     and node DEF     and node GHI       gt  This condition works perfectly fine   lt  xsl if gt

Try to use the empty   function    lt xsl if test  empty node ABC node    and empty node DEF node     gt       lt xsl text gt This should work lt  xsl text gt   lt  xsl if gt    This identifies ABC and DEF as empty in the sense that they do not have any child nodes  no elements  no text nodes  no processing instructions  no comments    But  as pointed out by  Ian  your elements might not be empty really or that might not be your actual problem - you did not show what your input XML looks like   Another cause of error could be your relative position in the tree  This way of testing conditions only works if the surrounding template matches the parent element of node or if you iterate over the parent element of node

Just for completeness and those unaware XSL 1 has choose for multiple conditions   lt xsl choose gt    lt xsl when test  quot expression quot  gt        some output       lt  xsl when gt    lt xsl when test  quot another-expression quot  gt        some output       lt  xsl when gt    lt xsl otherwise gt         some output        lt  xsl otherwise gt   lt  xsl choose gt
