Transformer - Sax - How to edit attributes?
Hi, i'm creating a transformer to edit links...
in my transformer i've the following method (i've simplified it to put
here...):
public void startElement(String uri, String name, String raw,Attributes
attr)throws SAXException {
//The following edits the value of the href attribute, and returns
a string with the new value...
String newAttrValue=transformLink(attr.getValue("href"), BASE_URL)
super.startElement(uri, name, raw, newAttrValue?????);
}
so, i need to simply copy the element, i've only to edit the href attribute
(I want to copy all the other attributes); the new value of href is in
"newAttrValue", but is a String... how to put the new href value as an
attribute together all the others?
Best Regards, Davide
Re: esql logicsheet and date
Posted by Jürgen Haas <no...@gmx.de>.
Hi,
maybe you should have a look in your database's manual. For example you can
use
INSERT INTO table (date_column) VALUES (now());
for inserting the current date (and time) into the column.
The result may be different, depending on the data type of the column. Type
date will result in 2004-01-03 and e. g. timestamp will be 2004-01-03
16:03:22.12345

esql logicsheet and date
Posted by Davide <da...@aliceposta.it>.
Hi!
I need to use esql to perform a query to put some data in a mysql db;
In the used table i have a Date column with timestamp(14) data type
In my xsp i get the date by <xsp:expr>new Date()</xsp:expr> but i think the
format is very differen. How can i use a compatible format? Are there some
utilities for dates and db?

That's because you are serializing as HTML. HTML is not
XML. THere is no closing tag for IMG necesary.
If you want XHTML, try
<map:serialize type="xml"/>
Older browsers will choke on the generated XHTML though.
There is no easy standard method to serialize XHTML, in a
way which generates both valid XML and code acceptable to
older browsers (<br /> instead of <br/>).

Trouble transforming EMPTY tag [Cocoon 2.1.4]
Posted by Matteo <tu...@email.it>.
Problem description:
When a try to transform an empty tag from an XML content to an HTML
formatting the resulting tag in the HTML page has not the closing part.
Code Example (this example is semplified but I tested it doesn't work
the same way the original problem):
here is the XML file with the content (test.xml):
<page>
<logo/>
</page>
here is the XSL stylesheet (test2html.xsl)
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="page">
<html>
<head>
<title>test</title>
</head>
<body>
<xsl:apply-templates select="logo"/>
</body>
</html>
</xsl:template>
<xsl:template match="logo">
<img src="data/image/oilogo.jpg" alt="logo"></img>
</xsl:template>
</xsl:stylesheet>
here is the sitemap entry for the page (extract from sitemap.xmap):
<map:pipeline>
<map:match pattern="test.htm">
<map:generate src="laos/xml/test.xml"/>
<map:transform src="laos/xsl/test2html.xsl"/>
<map:serialize type="html"/>
</map:match>
</map:pipeline>
here is the resulting html code from transformation (test.htm):
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>test</title>
</head>
<body>
<img alt="logo" src="data/image/oilogo.jpg"></body>
</html>
Any clue why the <img> doesn't end with <img/>?
Thanks in advance for the help!

Hi,

or this
<xsp:expr>request.getHeader("user-agent")</xsp:expr>

getting request parameters in the sitemap
Posted by Davide <da...@aliceposta.it>.
Hi, I have a problem...
I'm building something like a portal where i have a header generated by
cocoon and a body where i can have any xhtml page in the web...
I did it with cinclude aggregation but i had some "style" problems because
when the web page had a css changed also the style of the header. So i want
to use frames....
to retreive the web page i think to use the ws proxy generator; i need this
because i want also to apply transformation on if; my pipeline for wsproxy is:
<map:match pattern="body">
<map:act type="auth-protect">
<map:parameter name="handler" value="navigation"/>
<map:parameter name="use-request-parameters" value="true"/>
<map:generate type="proxy" label="xml" src="????????"/>
</map:act>
</map:match>
i call it with a "link" param containing the url, for example:
body?link=www.site.org
My problem is how to use the value of the link param as value for the src
param of the wsproxy generator?
Best Regards, Davide

nope, you have to pass an instance of Attributes there, not a String
the odd thing about the Attributes interface is that it doesn't allow to
modify the set, so you can't modify the atts that were passed in...
you can use a new instance of org.xml.sax.helpers.AttributesImpl though
see
http://java.sun.com/j2se/1.4.2/docs/api/org/xml/sax/helpers/AttributesImpl.html
for the API of that thing

so here goes
//warning uncompiled code
import org.xml.sax.helpers.AttributesImpl;
..
public void startElement(String uri, String name, String raw, Attributes
attr) throws SAXException {
..
AttributesImpl atts = new AttributesImpl(attr);
int hrefNdx = atts.getIndex("href");
String oldHrefValue = atts.getValue(hrefNdx);
String newHrefValue = transformLink(oldHrefValue , BASE_URL);
atts.setValue(hrefNdx, newHrefValue);
..
}
