break a for loop

lxu · January 14th, 2004, 02:17 PM

for loop through each record in the list_1
   for loop through each record in the list_2
      if list_1:Id = list_2:Id
         output the record of list_2

      else if list_1:Id cannot be FOUND in list_2 (means that
         after each node in the entire list_2 has been checked and
         still not found)
         output something like <tag-name xsi:nil = "true"/> (only one
                  output instead of print it out each time when
                  list_1:Id !=list_2:Id)

I know that there is no "break" in xslt for the for-loop. How can I get this?

Any hint and tip are appreciated.

I don't have the solution you asked for but I can suggest this. You can compare sets directly without looping. If you ask whether a node is equal to a node set you get true if there exists in that set a node whose string value is the same as the one of the single node. If you test whether they are not equal then you test that at least one node in the set does not equal that of the single node. You can also test whether no nodes are equal using not function.

Examples:

Use this data

Code:

<data>
  <items>
    <item id="id1">Item One</item>
    <item id="id2">Item Two</item>
    <item id="id3">Item Three</item>
    <item id="id4">Item Four</item>
  </items>
  <target1 id="id3"/>
  <target2 id="id5"/>
</data>

Run with this stylesheet:

Code:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/"><xsl:text>#x0a;</xsl:text>    
    target1/@id = items/item/@id: <xsl:value-of select="data/target1/@id = data/items/item/@id"/><xsl:text>#x0a;</xsl:text>
    target1/@id != items/item/@id: <xsl:value-of select="data/target1/@id != data/items/item/@id"/><xsl:text>#x0a;</xsl:text>  
    not(target1/@id = items/item/@id): <xsl:value-of select="not(data/target1/@id = data/items/item/@id)"/><xsl:text>#x0a;</xsl:text>
    *****************
    target2/@id = items/item/@id: <xsl:value-of select="data/target2/@id = data/items/item/@id"/><xsl:text>#x0a;</xsl:text>
    target2/@id != items/item/@id: <xsl:value-of select="data/target2/@id != data/items/item/@id"/><xsl:text>#x0a;</xsl:text>  
    not(target2/@id = items/item/@id): <xsl:value-of select="not(data/target2/@id = data/items/item/@id)"/><xsl:text>#x0a;</xsl:text>    
  </xsl:template>
</xsl:stylesheet>

One more question:

Here is my code in a xslt file,
<xsl:stylesheet xmlns:xsl=http://www.w3.org/1999/XSL/Transform xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">
<xsl:output method="xml" omit-xml-declaration="yes"/>
â¦
â¦
<xsl:element name="Part-MaterialDefiningDocument">
   <xsl:attribute name="xsi:nil">
       <xsl:value-of select='true'"/>
   </xsl:attribute>
</xsl:element>

â¦
â¦
</xsl:stylesheet>

Here is the output,
<Part-MaterialDefiningDocument xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true"/>

I want to the output to be in this way,
<Part-MaterialDefiningDocument xsi:nil="true"/>

How can I get rid of xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" from my output

Thanks for the helps!

You can't, you're using xsi:nil in the output so the namespace needs declaring.
