The sample script:
<HTML>
<body>
<script>
fred = "<img src='a.gif'></img>"
</script>
</body>
</HTML>
generates the following output from parser.cmd:
Tag (0[0,0],6[0,6]): HTML
Txt (6[0,6],10[1,2]): \n
Tag (10[1,2],16[1,8]): body
Txt (16[1,8],20[2,2]): \n
Tag (20[2,2],28[2,10]): script
Txt (28[2,10],57[3,27]): \n fred = "<img src='a.gif'>
End (57[3,27],57[3,27]): /script
End (57[3,27],63[3,33]): /img
Txt (63[3,33],68[4,2]): "\n
End (68[4,2],77[4,11]): /script
Txt (77[4,11],81[5,2]): \n
End (81[5,2],88[5,9]): /body
Txt (88[5,9],90[6,0]): \n
End (90[6,0],97[6,7]): /HTML
Txt (97[6,7],101[8,0]): \n\n
It looks like the closing tag is being recognised - though the opening
tag is not.
Is this a bug, or have I misunderstood something?

For parsing bad script like this you probably want to set the static boolean value org.htmlparser.scanners.ScriptScanner.STRICT to false. See the explanation in the ScriptScanner.java file. sebb wrote: >The sample script: > ><HTML> > <body> > <script> > fred = "<img src='a.gif'></img>" > </script> > </body> ></HTML> > >generates the following output from parser.cmd: > >Tag (0[0,0],6[0,6]): HTML > Txt (6[0,6],10[1,2]): \n > Tag (10[1,2],16[1,8]): body > Txt (16[1,8],20[2,2]): \n > Tag (20[2,2],28[2,10]): script > Txt (28[2,10],57[3,27]): \n fred = "<img src='a.gif'> > End (57[3,27],57[3,27]): /script > End (57[3,27],63[3,33]): /img > Txt (63[3,33],68[4,2]): "\n > End (68[4,2],77[4,11]): /script > Txt (77[4,11],81[5,2]): \n > End (81[5,2],88[5,9]): /body > Txt (88[5,9],90[6,0]): \n > End (90[6,0],97[6,7]): /HTML >Txt (97[6,7],101[8,0]): \n\n > >It looks like the closing tag is being recognised - though the opening >tag is not. > >Is this a bug, or have I misunderstood something? > >------------------------------------------------------------------------- >Take Surveys.

Thanks for the quick reply. I'll give it a try. However, I'm not sure why the script example is bad. It is not enclosed in "<!--" and "// -->", but AIUI those are only needed as a work-round for older browsers that did not understand the <script> tag.

Sorry, my bad - I've now read the document referenced in the scanner source, and I see that "</" acts as the terminator unless suitably hidden. S.

FYI: I've now tested the parser using ScriptScanner.STRICT=false and that solved the "problem". Thanks again.
