Hi

I am new to XSLT.

here is my XML
<books>
  <book id = "1" pub-id = "" isenglish = "Yes" author = "abc1">History1</book>
   <book id = "2" pub-id = "" isenglish = "Yes" author = "abc2">History2</book>
   <book id = "3" pub-id = "" isenglish = "Yes" author = "abc3">History3</book>
   <book id = "4" pub-id = "" isenglish = "No" author = "abc">History4</book>
   <book id = "5" pub-id = "" isenglish = "Yes" author = "abc1">History5</book>
   <book id = "6" pub-id = "" isenglish = "No" author = "abc2">History6</book>
   <book id = "7" pub-id = "1" isenglish = "Yes" author = "abc4">History7</book>
   <book id = "8" pub-id = "" isenglish = "Yes" author = "abc5">History8</book>
</books>

using following key i can choose all booknodes where isenglish attribute value is Yes.
  <xsl:key name="bookByLanguage" match="book[@isenglish="Yes"]" use="id"/>

But i need to choose all book nodes where isenglish attribute value is Yes and pub-id is equal to blank.

Can anyone please help me to write this match where two conditions are checked at once.

Thanks in advance..

Single quotes inside your attributes. Use 'and' to have two conditions.

<xsl:key name="booksEnglishNoPub" match="book[@isenglish='Yes' and @pub-id='']" use="id"/>

/- Sam Judson : Wrox Technical Editor -/

<xsl:key name="bookByLanguage" match="book[@isenglish="Yes"]" use="id"/>

I suspect you don't want to do that. xsl:key declares an index; the key() function uses the index to do a search. This particular declaration allows you to find an English book quickly if you know its id. But the id appears to be unique across all books, so if you know its id, you can find it without knowing whether or not it is English: using match="book" would give the same result.

I think I need to understand your requirements better.
