Parsing Text Between Two Empty XML Elements in Objective C - iphone

I already know how to parse XML Elements that contain content (<this> Content </this> in Objective C but I am currently using a web service that returns the content I need in between two closed elements (<begin-paragraph/> The content I need <end-paragraph/>) I have been looking online for any examples of anyone else doing this, but I could not find anything. If anyone knows how to read between the two empty elements and would care to share, I would appreciate that very much.

I have to say I regard that as an abuse of XML.
But I've checked and sadly it is well formed so NSXMLParser (which I assume is what you are using) should be able to cope with it.
You basically need to check which element you are in by handling the start element and end element events in your NSXMLParserDelegate. Then after receiving the –parser:didEndElement:namespaceURI:qualifiedName: message for begin-paragraph grab all the text you receive in -parser:foundCharacters: until you receive –parser:didStartElement:namespaceURI:qualifiedName:attributes: for end-paragraph

I don't know what the DOM conformance on the iPhone is like, but the general procedure would be:
Navigate to <begin-paragraph /> in your DOM.
Get the next sibling of that node. That is the content you need. (Node::nextSibling property)
If there are other elements in there that you want, keep collecting them by the same method, until you reach <end-paragraph />

manipulating Microsoft Word DOCX files that have links and track changes using Python

I have been using the excellent python-docx package to read, modify, and write Microsoft Word files. The package supports extracting the text from each paragraph. It also allows accessing a paragraph a "run" at a time, where the run is a set of characters that have the same font information. Unfortunately, when you access a paragraph by runs, you lose the links, because the package does not support links. The package also does not support accessing change tracking information.
My problem is that I need to access change tracking information. Or, more specifically, I need to copy paragraphs that have change tracking indicated from one document to another.
I've tried doing this at the XML level. For example, this code snippet appends the contents of file1.docx to file2.docx:
from docx import Document
doc1 = Document("file1.docx")
doc2 = Document("file2.docx")
doc2.element.body.append(doc1.element.body)
doc2.save("file2-appended.docx")
When I try to open the file on my Mac for complicated files, I get this error:
But if I click OK, the contents are there. The manipulation also works without problem for very simple files.
What am I missing?
The .element attribute is really an "internal" interface and should be named ._element. In most other places I have named it that. What you're getting there is the root element of the document part. You can see what it is by calling:
print(doc2.element.xml)
That element has one and only one w:body element below it, which is what you get when with doc2.element.body (.xml will work on that too, btw, if you want to inspect that element).
What your code is doing is appending one body element at the end of another w:body element and thereby forming invalid XML. The WordprocessingML vocabulary is quite strict about what element can follow another and how many and so forth. The only surprise for me is that it actually sometimes works for you, I take it :)
If you want to manipulate the XML directly, which is what the ._element attribute is there for, you need to do it carefully, in view of the (complex) WordprocessingML XML Schema.
Unlike when you stick to the published API, there's no safety net once ._element (or .element) appears in your code.
Inside the body XML can be relationships to external document parts, like images and hyperlinks. These will only be valid within the document in which they appear. This might explain why some files can be repaired.

cakephp element not displaying

I have a number of form inputs inside an element as they are repeated in other forms, however it does not output the content of the element when i include it in a view. I can place "Die();" within the element and it will show everything up until that point including the inputs within the element. When checking the source code (without the "Die();") it seems to have disregarded everything within the element including formatting such as DIV's.
The only thing i can think is that cakephp does not like you setting a form in a view then including inputs to the form using elements, does any one know if this is the case, or know the actual reason why this is happening?
The answer is i'm an idiot and forgot to echo the element.... yeah.

Need to print out all links on a sidebar in selenium (xpath?)

I need to find any extra links and print them out. I started by doing:
get_xpath_count('//li/a')
and comparing it to the size of an array that holds the name of all the links for the sidebar. When the count is too high/low, I need to print out all the extra/missing links. I would like to make a list of the names so I can compare it to the array. I've tried a few things like get_text('//li/a'), which returns the name of the first. get_text('//li/a[1]) does the same, but any other index returns nothing.
Any ideas? Also, I need the name that's displayed on the link, not the actual href.
Edit* Also, i'm pretty new to selenium and Xpath. Please let me know if there's info I let out that is needed, or just any suggestions towards thew way I'm going about this.
I have been able to get this to work using CSS element locators. Since I use CSS selectors far more often than Xpath, I find it easier to always use them with Selenium as well.
$selenium->get_text("css=li a:nth-child(1)")
$selenium->get_text("css=li a:nth-child(2)")
$selenium->get_text("css=li a:nth-child(...)")
$selenium->get_text("css=li a:nth-child(n)")
Use:
(//li/a)[$someNumber]
this will get you the text of $someNumber-th //li/a in the XML document.
In order to know what values to use to substitute the $someNumber with, you need to know the total count of these elements:
count(//li/a)
This is in JAVA. You can use the same concept in perl
int totCountInPage=selenium.getXpathCount(//li/a);
for(int count=1;count<=totCountInPage;count++)
System.out.println(selenium.getText("xpath=//li[count]/a"));
This should print text inside the anchor links under all li tag.

How to change the SSRS input parameters position in report

My SSRS report contains 7 input parameters and while running my report the size of the parameter(i.e. length) is increasing.
One of my input parameter(drop down list) may contain 100 characters so the size is not constant but i want to place all parameters in 2 lines or 3 lines(in a row).
Now it is coming 2 parameters per a row
Please advice
As gbn indicates, it's not easy to change the built in report server method of presenting the parameters. SSRS likes to always use two parameters per line, presented in the order that they exist in the report (which must match the dependency order.)
So the alternatives that gbn mentions: Both involve building a "Wrapper" application: some custom code or a web page that you can code however you like to get the parameters. Then you call Reporting Services, either in code or by passing a formatted URL with your parameters. The report can be displayed in a frame, new window, or passed as a stream to where ever you'd like.
The URL access is pretty straightforward and reliable: I often use it either by hand (to create "favorites") or in code.

For what you are looking for, these might be more work than you expected, but they will be extremely flexible for your interface.

You can certainly do that, just right click on the RDL file in the solution explorer and select view code. then move the XML tags named <ReportParameter Name="Nameofparameter"> under <ReportParameters> according to where ever you want to position. And then save it. thats it!!!
The report parameters are kind of floating in values of 2, so if u have 4 report parameters then it will be shown as 1,2 next line 3,4. Best of luck!!
Use ASP.NET for the paramaters and a ReportViewer control or URL access to render. Seriously.
I don't know of any option to present parameters any way other then the default
I believe you could try using jQuery. The report parameters are rendered in a table under a div tag with class sqlrv-ParameterContainer. Write a jQuery or JavaScript function that will extract the full innerHTML from this div ie. the table content and then extract the table row information like the <label> or <input> tags.
Create your desired table structure with <table><tr><td>{extracted sections}</td><td></td></tr></table> or leave it to your requirement...
Then just append this new HTML structure in place of the original default structure.
In jQuery it will be like
$(".sqlrv-ParameterContainer").html();
which will give you the entire table structure that comes inside the parameter. Use XML parsing and get the input controls and all. Extract these controls as-is, don't change anything.
$(".sqlrv-ParameterContainer table").remove(); // it will remove the SSRS rendered default table from DOM
$(".sqlrv-ParameterContainer table").appendChild('<table><tr>......</tr></table>'); // Append your custom html structure here....
This was something that came to my mind quickly... I would suggest you test it... :)
This doesn't help the OP with SSRS-2008 but in case it helps others - Microsoft have improved this in SSRS 2016 - parameters can now be easily managed via the GUI in Report Builder / Visual studio:

Gracefully Halting NSXMLParser?

still new to XML parsing with the iphone so i have a few questions.
in my opinion, id like my iphone-app to have to request out to the internet as less as possible, so i have combined a few XMLs i had to a single, larger one. However when im parsing information out, it has some similar node-names (not at the same level obviously) however its still causing me issues when trying to parse out my custom objects.
so should i just keep my XML all combined and rename some nodes? or make 2 XML calls?
opinions?
You need to manually track the state of your tree as you parse. The parser will work through your document in sequence so if you have an XML structure like so:
<a>
<name>some text</name>
<b>
<name>some other text</name>
</b>
</a>
You need to keep track of when your "a" and "b" elements start and end to know what context you are in.
