XSLT - How to select XML Attribute by Attribute

Question

this is the structure of my source xml    lt root gt   lt DataSet Value  A  gt   lt Data Value1  1  Value2  anythingA1    gt   lt Data Value1  2  Value2  anythingA2    gt   lt Data Value1  3  Value2  anythingA3    gt   lt Data Value1  4  Value2  anythingA4    gt   lt Data Value1  5  Value2  anythingA5    gt   lt  DataSet gt   lt  root gt    from which I like to create some variables e g  from all with Value1  2  and all with Value1  5  should result myVar1 with anythingA2 and myVar2 with anythingA5  My approch looks like this   lt xsl variable name  myVarA  select   DataSet Data   Value1  2    Value2    gt    but of course is not working since Value2 is no child of Value1   thanks for any hints in advance

There are two problems with your xpath - first you need to remove the child selector from after Data like phihag mentioned   Also you forgot to include root in your xpath   Here is what you want to do   select   root DataSet Data  Value1  2    Value2

Try this  xsl variable name  myVarA  select    DataSet Data  Value1  2    Value2    gt    The      will search for DataSet at any depth

I would do it by creating a variable that points to the nodes that have the proper value in Value1 then referring to t   lt xsl variable name  myVarANode  select  root  DataSet Data  Value1  2      gt   lt xsl value-of select   myVarANode  Value2   gt    Everyone else s answers are right too - more right in fact since I didn t notice the extra slash in your XPATH that would mess things up   Still  this will also work   and might work for different things  so keep this method in your toolbox

Just remove the slash after Data and prepend the root    lt xsl variable name  myVarA  select   root DataSet Data  Value1  2    Value2   gt

Note  using    at the beginning of the xpath is a bit CPU intensitve -- it will search every node for a match   Using a more specific path  such as  root DataSet will create a faster query
