[dom4j-dev] DocumentHelper.parseText data corruption after <

[David Frankson]

After some odd data corruption errors in my app, I tracked it down to
dom4j and managed to simplify the error to a short reproducable (with
1.6.1) case.  After enough attributes that include a > or <,
dom4j starts to mess up and duplicate parts of the data from one
attribute into the value of another.

<?xml version="1.0" encoding="UTF-8"?>
<Test test1="11111 &lt;" test2="22222 &lt;" test3="33333 &lt;"
test4="44444 &lt;" test5="55555 &lt;" test6="66666 &lt;" test7="77777
&lt;" test8="88888 &lt;" test9="99999 &lt;" test10="101010101010 &lt;"
/>


becomes:

<?xml version="1.0" encoding="UTF-8"?>
<Test test1="11111 &lt;" test2="22222 &lt;" test3="33333 &lt;"
test4="44444 &lt;" test5="55555 &lt;" test6="66666 &lt;" test7="88888
&lt;" test8="88888 &lt;" test9="1010101" test10="101010101010 &lt;"/>


when passed through dom4j.  Notice test7 and test 9 are corrupted with
some of the value from test8 and test10 respectively.  I've never dug
into the dom4j code before, could someone give me a tip on where to
look to troubleshout this very weird and destructive error?






Test program:

import org.dom4j.*;

public class ParseTest
{
       public static String xmlString = "<?xml version=\"1.0\"
encoding=\"UTF-8\"?><Test test1=\"11111 &lt;\" test2=\"22222 &lt;\"
test3=\"33333 &lt;\" test4=\"44444 &lt;\" test5=\"55555 &lt;\"
test6=\"66666 &lt;\" test7=\"77777 &lt;\" test8=\"88888 &lt;\"
test9=\"99999 &lt;\" test10=\"101010101010 &lt;\" />";

       public static void main(String[] args) throws Exception
       {
               System.out.println(xmlString);
               Document xml = DocumentHelper.parseText(xmlString);
               System.out.println(xml.asXML());
       }
}
