XSLT HTML output escaping problem

I am having problems with JAXP XSLT output escaping in HTML. I have an XML document which correctly escapes &, <, > etc (eg: &amp). However, when I transform the document the XSLT processor is escaping these values again. This means that the HTML output contains &amp; where the XML document contains & (for example). Surely correctly escaped characters in the XML should be left alone? Or should the XML document not contain escaped characters? In my understanding special characters in text nodes of XML documents should be escaped. Obviously a work around is to disable output escaping on these nodes but that is a real pain to have to do each time you pull a value through from the XML document. I'm confused as to what format the XSLT processor expects the XML to be in in relation to escaping of elements. Any information gratefully accepted!
Thanks.

Sorry! I was getting confused - the special characters were being escaped twice before they reached the XSLT processor. It looks like the processor will leave alone escape sequences that are already in the XML when it transforms to HTML.

  • 9iR2 XSLT: disable-output-escaping bug if  input is escaped

    If my interpretation of XSLT standards is correct, the "disable-output-escaping" attribute in the following example should output <table width="100%"> before the first attribute of the current element, and </table> after the last one. The overall result will be a valid HTML table. This is what happens if my browser (IE 5.5 SP2) or XMLSpy does the transform.
    In 9iR2 (and also in 9iR1), however, the actual output is &lt;table width="100%"&gt; and &lt;/table&gt;.
    Is this a (known) bug ??

  • Reports 3/6i HTML Output Print problem

    Hi!
    I am using Reports 3 to generate HTML output but when I print this HTML output, it does not break at Oracle Reports Page break. It looks like the browser takes its default settings for margins. I am using IE 5.5.
    I tried the following options
    1. Using { page-break-after: always } option in 'After Page Value' of Report Escapes property (Report)
    2. Changing margin settings of browser, but was not able to change them to 0.
    I want to print the HTML report with page breaks where Oracle marks as Page Break.
    If possible, Please do write me at [email protected]
    Thanks,
    Praveen Kumar

    Praveen,
    When you generate a HTML page in Reports, you are generating a single page document that is then intepretted by the browser. You are correct that when you then print this page from the browser then it will not necessarily break at the same point as the reports page breaks.
    The only way to guarantee that you will get the same breaks is to use a different format. Most commonly people use PDF format when they want the printed page to match exactly what's on the screen. Alternatively you could include a link on the HTML rendition of the report that resubmits the report to the server but instructs the server to print the report directly.
    Hope this helps,
    Danny

  • XSL disable-output-escaping problem

    When using the Java xslsample example to perform an XSLT transformation, we are trying to generate characters such as '<' in the output stream. However the following code fragment taken from the XSLT working draft:
    <xsl:text disable-output-escaping="yes"><</xsl:text>
    generates &#60; to the output stream.
    Any ideas?

    Never mind! I found the overloaded ProcessXSL member functions that output rather than transform.
    All cool now!

    Not a standard feature of XSLT. But Michael Kay's XSLT implementation, SAXON, provides that as an extension. Get it here:

  • Using Custom XSLT File for html output file

    Hi all
    I have probably rather a silly question but I have not found a solution yet.
    I would like to use a custom XSLT file, which I already have and is working, within a Biztalk Map. The custom XSLT is generating a html file out of an xml file. However I'm not able to succeed so far because I have probably some issues in defining the correct
    target schema. 
    The output that I get at the moment is just a duplicate of the input, probably because I have used the schema for source and target.
    So my question is, how do I create a html file out of an xml with a custom XSLT file?
    Sorry if this is a nooby question but I couldn't find an answer.

    Hi Jerome,
    Sorry, your question is not very clear. "I would like to use a custom XSLT file, which I already have and is working, within a BizTalk Map. The custom XSLT is generating a html file out of an xml file" -  You have an XSLT which you use for map and how
    its generating a HTML file? Are you using something like this?
    Changing an XML Response to an HTML output using a Map
    If your requirement is to output the html file from the received XML file using XSLT, then use a custom pipeline at send port like XSLT Transform Component and provide the XST which would change the XML to HTML. Here is an example of an XST which I have
    used in the past, which converts the received OrderResponse XML to nicely formatted HTML.

  • Getting question marks in html output when XML sourced from a CLOB...

    I have noticed a number of other unanswered questions on the
    same subject in this forum. Can someone at Oracle shed some
    light on this problem?...
    I store XML in CLOBS which contain a lot of &eacute; &ouml;
    characters. When using XSQL to select the XML from the CLOB I
    have to apply a stylesheet to the XSQL (myFile.xsql) with
    disable-output-escaping ="yes" in order to output well formed
    XML.
    I then call the XSQL file from inside another stylesheet i.e.
    <xsl:variable name="sample" select="document(myFile.xsql)"/>
    <xsl:template match="/">
    <xsl:for-each select="$sample">
    <html>
    <body>
    <title>
    <xsl:value-of select="/page/title"/>
    </title>
    </body>
    </html>
    etc...
    I use <xsl:for-each select="$sample"> to output the XML I need,
    within the HTML. The problem is though if "&eacute;" appears in
    the /page/title node the output in HTML appears as a question
    mark.
    Its important to note as well that the stylesheet I apply to
    myFile.xsql starts with:
    <xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output doctype-system="/myFile.dtd" indent="yes"/>
    etc..
    and myFile.dtd has <!ENTITY eacute "&#x000E9;"> in order to
    validate &eacute; in the CLOB.
    I don't have this problem when the &eacute; character is stored
    in a VARCHAR2 column and the VARCHAR2 column is in the same
    select statement as the CLOB in the XSQL file. This outputs in
    my HTML just fine. What am I missing here?
    Shaun

    I parse the XML doc into a domdocument and then loop through using xpath.valueof to pull the individual values from the nodes and then build a generic insert. It works quite well with a small number of columns. I'm not sure how it would work with a lot of columns. You can get code examples from Steve Muench's book "Developing Oracle XML Applications".

  • Xml/html to jsp - problem with quotes in attribute values

    I am trying to convert a static html document into a jsp using an xsl stylesheet, but run into problems trying to use the jsp expression syntax inside of attribute values.
    Here is a sample of the source file:
    <input type="text" name="firstName" value=""/>
    Here is what I want the resulting jsp file to look like:
    <input type="text" name="firstName" value="<jsp:expression>customer.getField("firstName") </jsp:expression>">
    Here is what part of my stylesheet looks like:
    <xsl:template match="input">
    <xsl:copy>
    <xsl:copy-of select="@type"/>
    <xsl:copy-of select="@name"/>
    <xsl:attribute name="value">
    <xsl:text disable-output-escaping="yes"><jsp:expression></xsl:text>
    <xsl:text disable-output-escaping="yes">customer.getField(</xsl:text>
    <xsl:text disable-output-escaping="yes">"</xsl:text>
    <xsl:value-of select="@name"/> ")
    <xsl:text disable-output-escaping="yes">")</xsl:text>
    <xsl:text disable-output-escaping="yes"></jsp:expression></xsl:text>
    </xsl:attribute>
    </xsl:copy>
    </xsl:template>
    The problem i have is with the <%= customer.getField("firstName") %>. I have tried several different ways of inserting the double quotes around firstName, but no matter what I try, it always uses the entity reference instead of actually putting the " character. The jsp container will not accept the entity.
    I am assuming that the problem is with trying to place double quotes inside of an attribute value. Any ideas how to get around this?
    Thanks
    David

    Which App Server are you using?
    You should just be able to escape the double quotes.
    If that doesn't work, it's a bug in the app-server.
    Alternatively, you can use single quotes around the
    attribute value.
    Hope that helps,
    AlexSorry, I'm an idiot. By escaping you meant the unicode character escape "\u0022". I had not tried that. However, once i realized what you meant, I tried it, and it worked. Thanks for your help.

  • Disable-output-escaping and named templates

    I am trying to combine two parts of Steve book, the "features" example that requires disable-output-escaping because the text in the db contains html, and the titledboxes xsl which is called a s a named template.
    Problem is that when I call a template passing the text from the db as a content param the html gets escaped regardless of the output escaping.
    I know why but I need to know a workaround that allows me to use templates and lets me keep html embeded in the db column.
    Rob

    This is Bug 1285505, "Disable-Output-Escaping Is Lost When Copying A Text Node" which has been fixed for the 9.0.1 release that will be posted to OTN in about the May timeframe.
    In the meantime, the workaround is to build two versions of your titled-box template, one which explicitly does disable-output-escaping when it writes the content to the output, and the other one that's like what you have now.

  • Missing a single space in html output

    Hello to all,
    take a look at the following code copied from a View
    <% DATA: eins TYPE STRING VALUE 'ClassEins',
             zwei TYPE STRING VALUE 'ClassZwei'. %>
    <span id="Test1" class="<%=eins%> ClassZwei">test it</span>
    <span id="Test2" class="ClassEins <%=zwei%>">test it</span>
    it works fine if compression is set to NONE, but if compression is set to 1 (remove spaces) or 2 (remove spaces, CR, LF) the html output looks like this:
    <span id="Test1" class="ClassEinsClassZwei">test it</span>
    <span id="Test2" class="ClassEins ClassZwei">test it</span>
    Where is the single space? What’s wrong? Why is the first space removed, but the second isn’t?

    Thilo,
    At this stage we are not planning a kernel patch, unless your business case is really pressing. (In which case update OSS message so that rethink why nein is the right answer.) We have actually spend a number of hours to find where this is stripped (by accident), and see that the price to fix this, is very high for us. The truth is that this is a minor problem that only happens when you active the additional compression, where our first suggestion would be to just skip the compression for this page. (All of this been said, we will keep it on the toDo list, and see if can get the resources at same stage to dive into kernel development again.)
    (Just for interest, not even myself could remember where some of this code is executed. Your problem provided a nice trip down memory lane!)
    As for the back tics, they are string literals, and are space sensitive in ABAP. An example:
      CONCATENATE 'a ' 'b ' 'c ' INTO s. --> s = "abc".
      CONCATENATE `a ` `b ` `c ` INTO s. --> s = "a b c ".
    The nice thing about this is that it is now possible to write in ABAP strings that contain <b>both</b> HTML and JavaScript all in one:
      s = `<body onload="myFunc('JSparm');">`.
    We use " and ' for the HTML and JavaScript, and the ` to build the ABAP string. Makes the Java colleagues just jealous of our writing style:)

  • Help: No Parameters, HTML Output from Java Servlet

    I have a Java Servlet that reads parameters passed from an HTML form and displays them to another HTML page. I know the servlet is being invoked; however, I am not seeing any HTML output. Sending the output to a file reveals the parameters are coming in as NULL as well.
    I attempted a simple sample app with the same results. Here is what I am running:
    The HTML Form:
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
    <HTML>
    <HEAD>
    <TITLE>Collecting Three Parameters</TITLE>
    </HEAD>
    <BODY BGCOLOR="#FDF5E6">
    <H1 ALIGN="CENTER">Collecting Three Parameters</H1>
    <FORM ACTION="ThreeParams">
    First Parameter: <INPUT TYPE="TEXT" NAME="param1"><BR>
    Second Parameter: <INPUT TYPE="TEXT" NAME="param2"><BR>
    Third Parameter: <INPUT TYPE="TEXT" NAME="param3"><BR>
    <CENTER><INPUT TYPE="SUBMIT"></CENTER>
    </FORM>
    </BODY>
    </HTML>
    The Java Code:
    public class ThreeParams extends HttpServlet {
    public void doGet(HttpServletRequest request,
    HttpServletResponse response)
    throws ServletException, IOException {
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
    String title = "Reading Three Request Parameters";
    out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
         "Transitional//EN\">\n" +
    "<BODY BGCOLOR=\"#FDF5E6\">\n" +
    "<H1 ALIGN=\"CENTER\">" + title + "</H1>\n" +
    "<UL>\n" +
    " <LI><B>param1</B>: "
    + request.getParameter("param1") + "\n" +
    " <LI><B>param2</B>: "
    + request.getParameter("param2") + "\n" +
    " <LI><B>param3</B>: "
    + request.getParameter("param3") + "\n" +
    "</UL>\n" +
    "</BODY></HTML>");
    What happens when I "submit" from the form is the same form reloads with the query string in the URL: "http://localhost:8080/ThreeParams/?param1=1&param2=2&param3=3"
    Any assistance with either (or both) would be thoroughly appreciated:
    a) why the parameters are not being passed correctly to the servlet
    b) why the HTML output page is not displayed
    Thanks in advance!
    - Steve
