XSLT1中处理含有默认名�U�空间声明的XML文档时的XPATH问题

刘佳 — Tue, 04 Jul 2006 15:43:00 GMT

XSLT1中��用XPATH对含有默认名�U�空间声明的XML文档�q�行查找时是查不出内容的

例如对于
<requestHierarchySelectResult xmlns=http://www.lightcc.com/ns xmlns:cs="http://www.customsolids.com">
    <request>
        <created_dt>05/05/2000 00:00:00</created_dt>
        <created_tm>01/01/1900 14:02:46</created_tm>
        <cs:request_id>100002</cs:request_id>
    </request>
</requestHierarchySelectResult>
应用
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
   xmlns="http://www.lightcc.com/ns"
   xmlns:cs="http://www.customsolids.com">
   <xsl:template match="/">
      <root><xsl:apply-templates select="/*/request"/></root>
   </xsl:template>
   <xsl:template match="*|@*|node()"/>
   <xsl:template match="request">
      <gotHere><xsl:value-of select="."/></gotHere>
   </xsl:template>
</xsl:stylesheet>
是没有效果的.
需要给默认的名�U�空间指定一个前�~�
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
   xmlns:lc="http://www.lightcc.com/ns"
   xmlns:cs="http://www.customsolids.com">
   <xsl:template match="/">
       <root><xsl:apply-templates select="/*/lc:request"/></root>
   </xsl:template>
   <xsl:template match="*|@*|node()"/>
   <xsl:template match="lc:request">
      <gotHere><xsl:value-of select="."/></gotHere>
   </xsl:template>
</xsl:stylesheet>
据说XSLT2和XPATH2会解册��个问�?br />

��目中用到XMLBeans做XML的数据绑定工�?但是发现生成的代码中的selectPath�q�不工作,调查后发现要使用SAXON,但是下蝲最新版后发��C��然不能正常工�?又经�q�调查得以解�?

XMLBeans2.2版是和saxon�?.6.1版一起工作的。最初的8.7和GOOGLE到的解决�Ҏ��中�ؓ2.0版准备的8.1都不�?br />XMLBeans2.2:
http://mirror.vmmatrix.net/apache/xmlbeans/binaries/

saxon 8.6.1:
http://jaist.dl.sourceforge.net/sourceforge/saxon/saxonb8-6-1.zip

xpath查询臛_��需�?saxon8.jar saxon8-dom.jar saxon8-xpath.jar才能正常工作
�~�少saxon8.jar会报如下错误

java.lang.RuntimeException: Trying XBeans path engine... Trying XQRL... Trying Saxon... FAILED on $this/data[@name='data2']
at org.apache.xmlbeans.impl.store.Path.getCompiledPath(Path.java:131)
at org.apache.xmlbeans.impl.store.Path.getCompiledPath(Path.java:91)

at test.main(test.java:16)
Exception in thread "main"

只放saxon8.jar也是不正��的.�~�少其他2个jar查询�l�果会不正确

��单测�?
SCHEMA:


   rootcomment




















XML:

  value1
  value2
  value3

jest.java

import java.io.File;

import noNamespace.DatasType;
import noNamespace.RootDocument;

import org.apache.xmlbeans.XmlObject;

public class test {
final static String NS_DECLEAR = "";
public static void main(String[] args) throws Exception {
  RootDocument doc = RootDocument.Factory.parse(new File("z:\\test.xml"));

  DatasType datas = doc.getRoot().getDatas();

  XmlObject[] objs = datas.selectPath("$this/data[@name='data2']");

  for (int i = 0; i < objs.length; i++) {
   System.out.println(objs[i]);
  }
}
}

输出:
