This is not how web developers process the DOM in HTML, especially on the client side.
Should I assume you are processing the value on the server side?
Either way, your post confused me. On the client side , we easily get the value attribute of the input DOM element with Javacript:
If on the server side, normally you use PHP or PERL and you get the attribute value when you submit on the browser to the server.
PHP Example:
or
We web developers do not process HTML files as big strings and use PERL or PHP or any language to extract a value; because this is easily done on both the client or server side with existing built-in methods.
Getting the value of an HTML DOM attribute does not require a script like you have written. Hidden values are normally submitted with HTML forms via the $_POST method.
This means on the server side, you would simple read the value of $_POST['value'] when the DOM element is submitted.
Hi,
Is it possible to delcare hashes in KSH the way we do it in Perl.
Like I want to declare something like:
fruits="Juicy"
fruits="healthy"
fruits="sour"
echo fruits
Ofcourse this piece of code does not work in KSH. Please let me know if there is a way of doing it in KSH.

Any clue to write something to a particular location in Perl?
Suppose
$line = ‘abc cde 1234”
How to write ( example string "test") on location 4 without parsing the whole line.
Output should be $line = ‘abctest 1234”
this is not search and replace. just to add substring into... (3 Replies)
Let's assume that I have a file with contents delimited by pipe:
"The mouse|ran up|the|clock"
"May|had a|little|lamb"
How would I use 'substr' to get the 3rd field. For example, "the" from the first line, and "little" from the second line?
# Loop over a file and read $LINE {

Hi Everyone,
$tmp="20090620231013";
$tmp = substr($tmp,0,8)." ".substr($tmp,8,2).":".substr($tmp,10,2).":".substr($tmp,12,2);
So my output is:
20090620 23:10:13.
I only can think substr is easy, any perl can do this just one line very simple efficient one? :eek:

I have a command like this:
listdb ID923 -l |gawk '{if (substr($0,37,1)==1 && NR == 3)print "YES" else if (substr ($0,37,1)==0 && NR == 3) print "NO"}'
This syntax doesn't work. But I was able to get this to work:
listdb ID923 -l |gawk '{if (substr($0,37,1)==1 && NR == 3)print "YES"}'

xml::dom::attr
XML::DOM::Attr(3pm) User Contributed Perl Documentation XML::DOM::Attr(3pm)NAME
XML::DOM::Attr - An XML attribute in XML::DOM
DESCRIPTION
XML::DOM::Attr extends XML::DOM::Node.
The Attr nodes built by the XML::DOM::Parser always have one child node which is a Text node containing the expanded string value (i.e.
EntityReferences are always expanded.) EntityReferences may be added when modifying or creating a new Document.
The Attr interface represents an attribute in an Element object. Typically the allowable values for the attribute are defined in a docu-
ment type definition.
Attr objects inherit the Node interface, but since they are not actually child nodes of the element they describe, the DOM does not con-
sider them part of the document tree. Thus, the Node attributes parentNode, previousSibling, and nextSibling have a undef value for Attr
objects. The DOM takes the view that attributes are properties of elements rather than having a separate identity from the elements they
are associated with; this should make it more efficient to implement such features as default attributes associated with all elements of a
given type. Furthermore, Attr nodes may not be immediate children of a DocumentFragment. However, they can be associated with Element nodes
contained within a DocumentFragment. In short, users and implementors of the DOM need to be aware that Attr nodes have some things in com-
mon with other objects inheriting the Node interface, but they also are quite distinct.
The attribute's effective value is determined as follows: if this attribute has been explicitly assigned any value, that value is the
attribute's effective value; otherwise, if there is a declaration for this attribute, and that declaration includes a default value, then
that default value is the attribute's effective value; otherwise, the attribute does not exist on this element in the structure model until
it has been explicitly added. Note that the nodeValue attribute on the Attr instance can also be used to retrieve the string version of the
attribute's value(s).
In XML, where the value of an attribute can contain entity references, the child nodes of the Attr node provide a representation in which
entity references are not expanded. These child nodes may be either Text or EntityReference nodes. Because the attribute type may be
unknown, there are no tokenized attribute values.
METHODS
getValue
On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their val-
ues.
setValue (str)
DOM Spec: On setting, this creates a Text node with the unparsed contents of the string.
getName
Returns the name of this attribute.
