I am trying to transform xml into c++ code. I want to put the source tree in c++ comments (/* ... */) so that people know where the c++ code was transformed from.

For example:
In xml:
<mylist>
   <item>foo</item>
   <item>bar</item>
</mylist>

In c++ code
/*
 Following code was created from xml source tree:
 <mylist>
   <item>foo</item>
   <item>bar</item>
 </mylist>
*/
std::vector<std::string> mylist;
mylist.push_back("foo");
mylist.push_back("bar");

However there is one problem bothering me. If in a xml source tree, any string contains substring "*/", it will break the c++ comment in c++ code.

Is there anyway I can recursively check node in the source tree to see if there is any string containing "*/"?

Thanks.

Not exactly sure what your xslt is, but I'm assuming you're using the xsl:copy-of or xsl:copy to copy the xml, correct?

You could do a recursive copy, something like:
<xsl:copy>
  <xsl:apply-templates mode="copy"/>
</xsl:copy>
and whenever you hit a text node, check if it contains the string */ by using the contains function. eg.
<xsl:if test="contains(., '*/')">

Ok, a simple version. Say I want to copy a source tree and put it between "/*" and "*/", only if the tree doesn't contain any node that has sub-string "*/".

The xslt is simply:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"/>
<xsl:template match="/">
/*
<xsl:copy-of select="."/>
*/
</xsl:template>
</xsl:stylesheet>

I want to be able to detect "*/" in the xml, output a warning message if there is any "*/".

I think the hard thing is doing the detection recursively. Because I can't assume any knowledge on the tree structure.

How abouit using contains() to check the text value of the source tree?

e.g

xml:
<foo>
  <bar>something</bar>
  <bar>
     <comment>/* comment */</comment>
  </bar>
</foo>

xsl:
<xsl:template match="foo">
  <xsl:if test="contains(., '*/')">
    Warning - tree contains closing comment mark
  </xsl:if>
</xsl:template>

okay.
<xsl:template match="/">
/*
<xsl:copy>
  <xsl:apply-templates select="node()"/>
</xsl:copy>
*/
</xsl:template>

<xsl:template match="node()">
  <xsl:if test="contains(., '*/')>Warning, extra end comment in source</xsl:if>
  <xsl:copy>
    <xsl:apply-templates select="node()"/>
  </xsl:copy>
</xsl:template>

I'm not sure where you want your warning though.
