I have a big xml file which i'm parsing using jscript. I have used the following code to load the xml
var xmlDoc = Sys.OleObject("Msxml2.DOMDocument.6.0");
xmlDoc.async = false;
// Load xml data from a file
xmlDoc.load(this._studyDocPath);
Now if i use the following code
var text = this.xmlDoc.selectSingleNode(xPath);
text = node.text;
the text variable holds the innertext of a perticular tag. But if I have tag like this
<Text>ABCD </Text>
then the node.text returns me only the value 'ABCD' i.e. it automatically trims the space. But I dont need to trim any trailling spaces. I need the text as it is. How can I achieve that?
Looking forward to your response
Thanks in Advance
We can use node.firstChild.nodeValue with a null check on node.firstChild

I am testing some network packets of my Organisation's product. We already have custom plugins. I am trying to add some some more fields into those existing plugins (like conversion of 2 byte code to a string and assign it to a field)
Thankyou in advance for reading my query.

Wireshark version : 2.4.5 (organization's plugins dont work on latest wireshark application)

Problem statement:
I am able to add field and show value, but fieldname is not displayed as defined.
I cannot share the entire .lua file but i will try to explain What i did:
Below is the image where I have a field aprint.type. this is a two byte field. In .lua file, for display purpose it is appended with corresponding description using a custom function int_to_enum.
I want to add one more proto field aprint.typetext which will show the text.
What I did:
Added a protofield f_apr_msg_type_txt = ProtoField.string("aprint.typetxt","aprint_type_text") (Tried f_apr_msg_type_txt = ProtoField.string("aprint.typetxt","aprint_type_text",FT_STRING) also)
Below the code where subtree aprint.type is shown, added my required field as subtree:add(f_apr_msg_type_txt, msg_type_string) (Below is image of code extract)
I am able to see the text but field Name is shown as Wireshark Lua text (_ws.lua.text)
Normally displaying strings based on numeric values is accomplished by a value string lookup, so you'd have something like so:
local aprint_type_vals = {
[1] = "Foo",
[2] = "Bar",
[9] = "State alarm"
}
f_apr_msg_type = ProtoField.uint16("aprint.type", "Type", base.DEC, aprint_type_vals)
f_apr_msg_type_txt = ProtoField.string("aprint.typetxt","aprint_type_text", base.ASCII)
... then
local msg_type = tvb(offset, 2):le_uint()
subtree:add_le(f_apr_msg_type, tvb(offset, 2))
subtree:add(f_apr_msg_type_txt, tvb(offset, 2), (aprint_type_vals[msg_type] or "Unknown"))
--[[
Alternatively:
subtree:add(f_apr_msg_type_txt, tvb(offset, 2)):set_text("aprint_type_text: " .. (aprint_type_vals[msg_type] or "Unknown"))
--]]
I'm also not sure why you need the extra field with only the text when the text is already displayed with the existing field, but that's basically how you'd do it.
CONCLUSION:
For some reason the flow wouldn't let me convert the incoming message to a BLOB by changing the Message Domain property of the Input Node so I added a Reset Content Descriptor node before the Compute Node with the code from the accepted answer. On the line that parses the XML and creates the XMLNSC Child for the message I was getting a 'CHARACTER:Invalid wire format received' error so I took that line out and added another Reset Content Descriptor node after the Compute Node instead. Now it parses and replaces the Unicode characters with spaces. So now it doesn't crash.
Here is the code for the added Compute Node:
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
DECLARE NonPrintable BLOB X'0001020304050607080B0C0E0F101112131415161718191A1B1C1D1E1F7F808182838485868788898A8B8C8D8E8F909192939495969798999A9B9C9D9E9FA0A1A2A3A4A5A6A7A8A9AAABACADAEAFB0B1B2B3B4B5B6B7B8B9BABBBCBDBEBFC0C1C2C3C4C5C6C7C8C9CACBCCCDCECFD0D1D2D3D4D5D6D7D8D9DADBDCDDDEDFE0E1E2E3E4E5E6E7E8E9EAEBECEDEEEFF1F2F3F4F5F6F7F8F9FAFBFCFDFEFF';
DECLARE Printable BLOB X'20202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020202020';
DECLARE Fixed BLOB TRANSLATE(InputRoot.BLOB.BLOB, NonPrintable, Printable);
SET OutputRoot = InputRoot;
SET OutputRoot.BLOB.BLOB = Fixed;
RETURN TRUE;
END;
UPDATE:
The message is being parsed as XML using XMLNSC. Thought that would cause a problem, but it does not appear to be.
Now I'm using PHP. I've created a node to plug into the legacy flow. Here's the relevant code:
class fixIncompetence {
function evaluate ($output_assembly,$input_assembly) {
$output_assembly->MRM = $input_assembly->MRM;
$output_assembly->MQMD = $input_assembly->MQMD;
$tmp = htmlentities($input_assembly->MRM->VALUE_TO_FIX, ENT_HTML5|ENT_SUBSTITUTE,'UTF-8');
if (!empty($tmp)) {
$output_assembly->MRM->VALUE_TO_FIX = $tmp;
}
// Ensure there are no null MRM fields. MessageBroker is strict.
foreach ($output_assembly->MRM as $key => $val) {
if (empty($val)) {
$output_assembly->MRM->$key = '';
}
}
}
}
Right now I'm getting a vague error about read only messages, but before that it wasn't working either.
Original Question:
For some reason I am unable to impress upon the senders of our MQ
messages that smart quotes, endashes, emdashes, and such crash our XML
parser.
I managed to make a working solution with SQL queries, but it wasted
too many resources. Here's the last thing I tried, but it didn't work
either:
CREATE FUNCTION CLEAN(IN STR CHAR) RETURNS CHAR BEGIN
SET STR = REPLACE('–',STR,'–');
SET STR = REPLACE('—',STR,'—');
SET STR = REPLACE('·',STR,'·');
SET STR = REPLACE('“',STR,'“');
SET STR = REPLACE('”',STR,'”');
SET STR = REPLACE('‘',STR,'&lsqo;');
SET STR = REPLACE('’',STR,'’');
SET STR = REPLACE('•',STR,'•');
SET STR = REPLACE('°',STR,'°');
RETURN STR;
END;
As you can see I'm not very good at this. I have tried reading about
various ESQL string functions without much success.
So in ESQL you can use the TRANSLATE function.
The following is a snippet I use to clean up a BLOB containing non-ASCII low hex values so that it then be cast into a usable character string.
You should be able to modify it to change your undesired characters into something more benign. Basically each hex value in NonPrintable gets translated into its positional equivalent in Printable, in this case always a full-stop i.e. x'2E' in ASCII. You'll need to make your BLOB's long enough to cover the desired range of hex values.
DECLARE NonPrintable BLOB X'000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F202122232425262728292A2B2C2D2E2F303132333435363738393A3B3C3D3E3F';
DECLARE Printable BLOB X'2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E2E';
SET WorkBlob = TRANSLATE(WorkBlob, NonPrintable, Printable);
BTW if messages with invalid characters only come in every now and then I'd probably specify BLOB on the input node and then use something similar to the following to invoke the XMLNSC parser.
CREATE LASTCHILD OF OutputRoot DOMAIN 'XMLNSC'
PARSE(InputRoot.BLOB.BLOB CCSID InputRoot.Properties.CodedCharSetId ENCODING InputRoot.Properties.Encoding);
With the exception terminal wired up you can then correct the BLOB's of any messages containing parser breaking invalid characters before attempting to reparse.
Finally my best wishes as I've had a number of battles over the years with being forced to correct invalid message content in the "Integration Layer" after all that's what it's meant to do.
I'm trying to write something like rtf editor in BCB6 and I've encountered such problem while trying to add table to my RichEdit1:
RichEdit1->PlainText=true;
AnsiString ret=RichEdit1->Text;
ret.Insert(table, RichEdit1->SelStart);
RichEdit1->Text=ret;
RichEdit1->PlainText=false;
RichEdit1->Repaint();
This code adds formatted text (code of table) to the RichEdit1 instead of adding formatting code as plain text and displaying it like a table.
Am I doing it wrong, or it can be a problem with something else.
The PlainText property is only used by the Lines->LoadFrom...() and Lines->SaveTo...() methods, nothing else.
The Text property only operates on plain text. Reading the property extracts the RichEdit's textual content without formatting. Setting the property does not process RTF code at all, the RichEdit's textual content is replaced with the new text as-is.
If you want to insert RTF code into the RichEdit, especially if you don't want to overwrite the RichEdit's current content, you will have to use the EM_STREAMIN message directly. For example:
DWORD CALLBACK StreamInCallback(DWORD_PTR dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)
{
int numRead = reinterpret_cast<TStringStream*>(dwCookie)->Read(pbBuff, cb);
if (pcb) *pcb = numRead;
return 0;
}
TStringStream *strm = new TStringStream(table);
EDITSTREAM es = {0};
es.dwCookie = (DWORD_PTR) strm;
es.pfnCallback = &StreamInCallback;
SendMessage(RichEdit1->Handle, EM_STREAMIN, SF_RTF | SFF_SELECTION, reinterpret_cast<LPARAM>(&es));
delete strm;
Problem solved, formatting was not added because of table code was not in {} brackets, after adding them around table code and using SendMessage, program works well.
I have this situation in my strings.xml.
<string name="mensagem">Olá <b><i> {0} </i></b>,</string>
And in my code I do this:
string msg = String.Format(Resources.GetString(Resource.String.mensagem).ToString(), cliente.Nome.ToUpper());
lblNome.Text = Html.FromHtml(msg).ToString();
But the style tags (b,i) do not work. I need to concatenate words with and without style, so I need to do it in this way. I cant use setTypeface because I need to style individual words and after that, join those words on a sentence.
What is the way ?
Regards,
Marcelo.
You need to change your code to the following.
string msg = String.Format(Resources.GetString(Resource.String.mensagem).ToString(), cliente.Nome.ToUpper());
lblNome.TextFormatted = Html.FromHtml(msg);
Html.FromHtml(string).ToString() is just converting the formatted ISpannable back to a string so you are losing the formatting.
I am working from this example: http://jqueryui.com/demos/autocomplete/#remote and I am encoding the output like this:
$rows = array();
while($r = mysql_fetch_assoc($category_result))
{
$rows[] = $r;
error_log ("rows: ".$rows[0]);
}
echo json_encode($rows);
But the dropdown on the other side shows nothing. Here is my test page: http://problemio.com/test.php - if you enter "ho" it matches 2 results in the database, but they are not getting displayed for some reason. Any idea why?
Thanks!!
The properties should be named label and value. From the JQuery UI demo page you linked to:
The local data can be a simple Array of Strings, or it contains
Objects for each item in the array, with either a label or value
property or both. The label property is displayed in the suggestion
menu.
So you would need to rename category_name to label either in PHP or later on in your JavaScript source handler function. The latter would require you to replace the PHP URL with a callback function like in the remote example. That way you could get the data any way you want (e.g. by jQuery.getJSON()) and work with it before it gets handed over to the suggestion box.
Hope this helps.
Regarding your comment, this should do it:
$rows = array();
while ($r = mysql_fetch_array($category_result)) {
$rows[] = array("label" => $r["category_name"]);
}
echo json_encode($rows);
