Hello Fellows,
I've one XML and trying to access the specific CDATA on XML but when do
this, I capture all CDATAs nodes. See the XML and XSL code bellow:
First of all, there is no such thing as a CDATA node. CDATA is just a
nice way to write something so that you don't have to worry about
escaping all the < and other special characters. There's only text
nodes. So what you really appear to be asking for is a way to select
specific text nodes.
And the answer is yes, of course. Just select the text nodes and
apply-templates or get their value.
// -----------------------------xml -----------------------------
<?xml version="1.0" encoding="UTF-8"?>
<scripts>
<etps total="1">
<etp id="200">
<![CDATA[Trying accessing only this]]>
<nvgs>
<nvg id="201"><![CDATA[blablablablabla]]></nvg>
<nvg id="202"><![CDATA[blablablablabla]]></nvg>
</nvgs>
</etp>
</etps>
</scripts>
// -----------------------------xsl -----------------------------
//code's resume
<xsl:choose>
<xsl:when test="scripts/etapas/@total>0">
<table width="100%" id="SCRIPT">
<tr valign="top" style="font-weight:bold;">
<th width="40%">etp</th>
<th width="20%">nvg</th>
</tr>
<xsl:for-each select="scripts/etapas/etapa">
<tr valign="top">
<td comment="ETP">
<xsl:value-of select="."/><br/> <!--When I put the prefix "."
<!--the XSL return all CDATA nodes, including "nvgs"-->
No, it gets the value of the element, which is defined in the specs.
A quick summary would be all the text nodes of this element and all
the text nodes of its descendents. If you don't want to do that, get
<xsl:value-of select="text()" /> although my guess in this case you
want to get <xsl:value-of select="text()[1]" />. (or just
apply-templates on those if you do anything special with the text).
Is it necessary to create a node to CDATA ?
No, since it'll be turned into just escaped text via the parser. As
far as the processor is concerned, it's just a typical text node.
