[jira] Commented: (XALANJ-1969) xml:space not considered when
deciding which elements to strip
[ https://issues.apache.org/jira/browse/XALANJ-1969?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12776092#action_12776092 ]
Daniel B. commented on XALANJ-1969:
-----------------------------------
This bug still exists in Xalan-J 2.7.1.
By the way, the XSLT specification's section 3.4, Whitespace Stripping (at
http://www.w3.org/TR/xslt#strip), specifies the required behavior pretty clearly:
A text node is preserved if any of the following apply:
...
* An ancestor element of the text node has an xml:space attribute with a value of
preserve, and no closer ancestor element has xml:space with a value of default.

> Key: XALANJ-1969
> URL: https://issues.apache.org/jira/browse/XALANJ-1969
> Project: XalanJ2
> Issue Type: Bug
> Security Level: No security risk; visible to anyone(Ordinary problems in Xalan projects. Anybody can view the issue.)
> Components: Xalan-interpretive, XPath-function
> Affects Versions: 2.6
> Reporter: elharo
> Attachments: 91444.xml, 91444.xsl, node-lister.xsl

> This report is based on OASIS Microsoft test case Whitespaces__91444. In breif the expected output is 22, but the actual output is 7. I'm not sure 22 is correct, but I'm pretty sure 7 isn't. The stylesheet is as follows:
> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:my="http://my.com">
> <xsl:output omit-xml-declaration="yes" encoding="UTF-8" indent="no"/>
> <xsl:strip-space elements="*"/>
> <xsl:template match="/">
> <!-- Preceding query (selection) -->
> <preceding-count><xsl:value-of select="count(html/my:element/preceding::text())"/></preceding-count>
> </xsl:template>
> </xsl:stylesheet>
> If all white space nodes are stripped from the input document, then the expected output would be what Xalan gives:
> $ java -Xbootclasspath/p:/opt/xalan-j_2_6_0/bin/xalan.jar:/opt/xalan-j_2_6_0/bin/xercesImpl.jar:/opt/xalan-j_2_6_0/bin/xalansamples.jar org.apache.xalan.xslt.Process -IN 91444.xml -XSL 91444.xsl
> <preceding-count xmlns:my="http://my.com">7</preceding-count>~/Projects/XOM/datas$ sis-xslt-testsuite/TESTS/MSFT_Conformance_Tests/Whitespaces
> However, the input document contains a number of white space only nodes for which xml:space="true", and according to section 3.4 of thre XSLT spec, these node should be preserved regardless.
> FYI, libxslt shares this bug; i.e. it also gives 7 as the output.
