Henry Zongaro updated XALANJ-903:
---------------------------------
Priority: Critical
> infinite loop is generated in xsl:for-each
> ------------------------------------------
>
> Key: XALANJ-903
> URL: http://nagoya.apache.org/jira/browse/XALANJ-903
> Project: XalanJ2
> Type: Bug
> Components: Xalan-interpretive, transformation
> Versions: 2.3
> Environment: Operating System: Windows NT/2K
> Platform: PC
> Reporter: ruowei wu
> Assignee: Xalan Developers Mailing List
> Priority: Critical

> we used to use xalan 2.1.0 to transform, it's ok. but the problem happens in
> xalan 2.3.1 and jdk1.4 is having same problem. The result is like this:
> public String toString()
> {
> String result = "{";
> result += "name=";
> result += name;
>
> result += "name=";
> result += name;
>
> result += "name=";
> result += name;
>
> result += "name=";
> result += name;
>
> result += "name=";
> result += name;
>
> result += "name=";
> result += name;
>
> result += "name=";
> result += name;
> we check the xslt and find it's xsl:for-each that cause this problem. Here
> are
> the xml and xslt
