Question about the "<" Tag

[Ramo At Skuff]

Hi,

i try to get somethign like this:

xml:
<FormElement type="tx" character="text" id="tx_00_user" name="tx_00_user"
tabmember="loguser" mandat="y"  size="20" checkValue="isThisset" >


To parse with this line:

input.setAttribute("value", "<" + "?pho " +
attributes.getValue("checkValue") + " (\"" + attributes.getValue("name")  +
"\"); ?>");
                                                       

to get this:

<input type="text" id="tx_00_user" name="tx_00_user" class="mandatory"
size="20" value<?php isThisset ("tx_00_user"); ?>" />

But i get this:

<input type="text" id="tx_00_user" name="tx_00_user" class="mandatory"
size="20" value="<?php isThisset ("tx_00_user"); ?>" />


Is there a way or a trick to get the result i want?

Many thanks

ramo

Hi Ramo

Technically, you do have the result you want...

'<' is not valid content in attribute values (or in Element text....).
See the XML specification here:

http://www.w3.org/TR/2006/REC-xml-20060816/#sec-common-syn

where it indicates:
[10]       AttValue       ::=       '"' ([^<&"] | Reference)* '"' |  "'"
([^<&'] | Reference)* "'"

Basically, the characters < & and " are not allowed in attribute values.
The way to get these characters is to use XML 'excapes', or nore
formally called Entity Values.

Section http://www.w3.org/TR/2006/REC-xml-20060816/#syntax of the
specification shows how to represent the characters < and & in XML with
< and & respectively.

When an XML Parser (like SAX used in JDOM) reads the document, it will
reverse the escaped values < and & to the original values < and &.

Any other escape sequences in the XML file starting with & and ending
with ; will also be replaced with the appropriate values according to
Entity value definitions too. There are many other escapes like "
and > for " and >

Another way to put it: What you are trying to produce isn't XML, so you
shouldn't be using JDOM.
