java - using XSLT apply-template to descendents with different names -
"I am trying to use apply-templates for elements encapsulated within parent element but has different element name. In my example I want to apply it to /Author/Name/ elements and choose either of one whichever has a value. This task is continuation of another question I have asked.
I am using the following XML
<?xml version=""1.0"" encoding=""UTF-8""?>
<Author>
<Info>
<Name>
<FirstName>#3 bb***</FirstName>
<LastName>test</LastName>
</Name>
<Input>
<Item>##### 3 ??***</Item>
</Input>
</Info>
<Custom>Test</Custom>
</Author>
I am applying the following XSLT 1.0 using java. In above example I want template applied to firstName and lastName but show value in firstName since it is the first with a value.
<xsl:stylesheet version=""1.0""
xmlns:xsl=""http://www.w3.org/1999/XSL/Transform"">
<xsl:output method=""xml"" version=""1.0"" encoding=""UTF-8"" indent=""yes""/>
<xsl:variable name=""allowed-start-chars"">abcdefghijklmnopqrstuvwxyz</xsl:variable>
<xsl:variable name=""allowed-follow-chars"">0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ ?abcdefghijklmnopqrstuvwxyz-'.,/@&()!+</xsl:variable>
<xsl:template match=""/"">
<html>
<body>
<!-- Not sure how to use `xsl:choose` just added to show my intentions-->
<xsl:choose>
<xsl:when test="".."">
<div>
<xsl:apply-templates select=""Author/Name/FirstName""/>
</div>
</xsl:when>
</xsl:choose>
</body>
</html>
</xsl:template>
<!--used pipe to apply for two different elements but it does not work-->
<xsl:template match=""FirstName|LastName"">
<!-- find the first character eligible to be starting character -->
<xsl:variable name=""start-chars"" select=""translate(., translate(., $allowed-start-chars, ''), '')""/>
<xsl:variable name=""start-char"" select=""substring($start-chars, 1, 1)""/>
<!-- get text after the chosen starting character -->
<xsl:variable name=""tail"" select=""substring-after(., $start-char)""/>
<!-- remove unwanted characters from tail -->
<xsl:variable name=""fo"" select=""translate($tail, translate($tail, $allowed-follow-chars, ''), '')""/> <xsl:choose>
<!--only show if character remain after removing bad ones, and not empty-->
<xsl:when test=""string-length($start-char) > 0 and normalize-space(concat($start-char, $fo))"">
<xsl:value-of select=""normalize-space(concat($start-char, $fo))""/>
</xsl:when>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
The Java code is Stylizer class from Oracle tuorial page example, please refer the link for full code. I am running command-line sending xml and xslt files.
File stylesheet = new File(argv[0]);
File datafile = new File(argv[1]);
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse(datafile);
// Use a Transformer for output
TransformerFactory tFactory = TransformerFactory.newInstance();
StreamSource stylesource = new StreamSource(stylesheet);
Transformer transformer = tFactory.newTransformer(stylesource);
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);
I would appreciate again help on this one. As I am learning XSLT and I am also not sure what performance issue using approach
java xml xslt
