problem with xsl:for-each

[matatu]

Hi to everybody,

It's possible to exit from a cycle for-each?

I have this code:

1: <xsl:for-each select="field">
2: <xsl:variable name="tagfield" select="@tag"/>
3: <xsl:variable name="pos" select="position()"/>
4: <xsl:for-each select="/root/ass/istance">
5: <xsl:choose>
6: <xsl:when test="number($tagfield) != number(tag/@name)">
7: <xsl:call-template name="handle-tilde"/>
8: </xsl:when>
9: <xsl:when test="number($tagfield) = number(tag/@name)">
10: <xsl:apply-templates select="/root/record/fields/field[$pos]"/>
11: </xsl:when>
12: </xsl:choose>
13: </xsl:for-each>
14: <xsl:value-of select="' '"/>
15: </xsl:for-each>

if the condition to the line 9 are verified it has to jump to the
"field" element following. It's possible?

thanks for the possible answers

Hi,

Disclaimer : I have not executed the following. Try this :

<xsl:for-each select="field">
<xsl:variable name="tagfield" select="@tag" />
<xsl:variable name="pos" select="position()" />

<xsl:for-each select="/root/ass/istance[number($tagfield) !=
number(tag/@name)]">
<xsl:call-template name="handle-tilde" />
</xsl:for-each>

<xsl:value-of select="' '" />

<xsl:for-each select="/root/ass/istance[number($tagfield) =
number(tag/@name)]">
<xsl:apply-template select="/root/record/fields/field[$pos]" />
</xsl:for-each>
</xsl:for-each>

This is not equivalent in processing to what you want if your input
/root/ass/istance elements need to be processed in document order. If
not, then the logic should work.

I don't think that possible.

But this template should mimic the behaviour you want:

<xsl:for-each select="field">
<xsl:variable name="tagfield" select="number(@tag)"/>
<xsl:variable name="pos" select="position()"/>
<xsl:for-each select="/root/ass/istance[not($tagfield=
preceding-sibling::istance/tag/@name|tag/@name)]">
<xsl:call-template name="handle-tilde"/>
</xsl:for-each>
<xsl:choose>
<xsl:when
test="count(/root/ass/istance[$tagfield = number(tag/@name)])
&gt; 0">
<xsl:apply-templates select="/root/record/fields/field[$pos]"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="' '"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
