I am attempting to strip the HTML from an iframe using vbscript. Any decent way to do this? Here is the only suggestion I found online, and it is pulling the HTML from the main page, not the iframe:
pageHTML = ie.document.All("ExternalQuestionIFrame").Document.Body.innerHTML
ExternalQuestionIFrame is the name attribute. No ID tagged.
Perhaps try the iFrame's contentWindow.
Set myFrame = ie.document.getElementByID("ExternalQuestionIFrame")
Set internalContent = myFrame.contentWindow
pageHTML = internalContent.Document.Body.innerHTML
This can probably be cleaned up into a one-liner, but I like to set my objects a little piece at a time.

I have a task to render an HTML page with dynamic data and turn it into PDF, but, I have a problem achieving it.
def makepdf(request):
if request.POST:
chatvs = Competirors.objects.get(id = int(request.POST.get('competitor', '')))
jivo_staff = Manager.objects.get(id = int(request.POST.get('manager', '')))
business = Field.objects.get(id = int(request.POST.get('filed', '')))
business = business.link.all().order_by('?')[0:3]
context = {
"chatvs" : chatvs,
"jivo_staff" : jivo_staff,
"business" : business,
}
tmpl = get_template('marketing/jivopdf.html', )
html = tmpl.render(context)
# and i have a problem there with pdfkit
I was using Pdfcrowd API, but it cuts all CSS styles and does not look nice. As for vvwkhtmltopdf/pdfkit - I don't know how to make it a rendered HTML page, as it accesses only the url/file/string.
Is there a way to render ready HTML page?
Hard to say without knowing the error you get.
But what I can see from your code, if this is your real code. Looks like a spelling mistake in Competirors.objects.get, should probably be named Competitors.
And if you get the POST data from a form, you shouldn't use it directly.
Never trust user input...
I suggest you try weasyprint .
I have a base .docx for which I need to change the page header / footer image on a case by case basis. I read that python-docx does not yet handle headers/footers but it does handle Pictures.
What I cannot work around is how to replace them.
I found the Pictures in the documents ._package.parts objects as ImagePart, I could even try to identify the image by its partname attribute.
What I could not find in any way is how to replace the image. I tried replacing the ImagePart ._blob and ._image attributes but it makes no difference after saving.
So, what would be the "good" way to replace one Image blob with another one using python-docx? (it is the only change I need to do).
Current code is:
d = Document(docx='basefile.docx')
parts = d._package
for p in parts:
if isinstance(p, docx.parts.image.ImagePart) and p.partname.find('image1.png'):
img = p
break
img._blob = open('newfile.png', 'r').read()
d.save('newfile.docx')
Thanks,

There is no requirement to use python-docx. I found another Python library for messing with docx files called "paradocx" altought it seems a bit abandoned it works for what I need.
python-docx would be preferable as the project seems more healthy so a solution based on it is still desired.
Anyway, here is the paradocx based solution:
from paradocx import Document
from paradocx.headerfooter import HeaderPart
template = 'template.docx'
newimg = open('new_file.png', 'r')
doc = Document.from_file(template)
header = doc.get_parts_by_class(HeaderPart).next()
img = header.related('http://schemas.openxmlformats.org/officeDocument/2006/relationships/image')[0]
img.data = newimg.read()
newimg.close()
doc.save('prueba.docx')
I have a bit different task to do,
first, i have add an iframe tag dynamically, which i was able to do easily using the code->
function getFrame()
{
var iframeTA = document.createElement("IFRAME");
iframeTA.setAttribute("src", "iframeTakeAction.html");
iframeTA.style.width = "200px";
iframeTA.style.height = "200px";
document.getElementById("status").appendChild(iframeTA);
}
now, want i want to do is to access the elements of iframeTA (i.e. elements within the body tag of 'iframeTakeAction.html' which is the source of iframeTA),
something like this ->
iframeTA.body.getSomeElement......
Hope this kind of operation is possible, if so please put some light.
Thanks.
You should be able to access it with:
document.getElementById("TOUR IFRAME ID")
However, this only holds as long as your iframe src is a relative path on the same domain. If you change the domain then your browser will prevent you to do this.
When I want to render a picture, I send a request to the server with the associated picture to render. What's odd is how it's returned:
<img src="https://blargh.com/displayTemplate?templateid=template1">
Where that link is supposed to be the image data.
Using this, how can I transform that into an image that I can display to the user? This is for a facebook app, I can't just embed the HTML. It needs to be displayed inside my AS App as a Bitmap or Sprite or anything, really. Trying to convert it to a Bitmap or BitmapData have failed...
The only other information I can give is that my templateLoader is a Loaderand its .data is supposed to carry the HTML.
Something like this:
var data:String = '<img src="https://blargh.com/displayTemplate?templateid=template1">';
// grab the src attribute
var url:Array = data.match(/<img src=\"(.*?)\">/);
if (url.length > 1){
var loader:Loader = new Loader();
loader.load(new URLRequest(url[1]));
addChild(loader);
}
Use e4x. I'm not sure if you're getting a string or the result format on your service call is already XML, but if it's a string, you'd do something like this:
var imgXML:XML = XML(yourString);//yourString contains <img src="https://blargh.com/displayTemplate?templateid=template1">
link = imgXML.#src;
Then, look at the code Zevan posted for how to use a Loader if you're using just AS, or use it as the source for an Image control in Flex.
Looks like the server is providing you with a link that dynamically looks up the image based on the GET data you're passing to the server (the ?templateid=template1). Too bad you didn't paste in the real link so that this theory could be proven. Take the real link and copy out the http:// portion, enter it into your browser and if the image appears then this is indeed the case.
If this is true, then you want to extract the link from the tag. You could do this with a regular expression, like so:
/\?)"(.?)"(.*)/
If you ran that regex against the full tag like you've provided above, then capture group 2 will contain just the HTTP link. You can then use a Loader object to fetch the image so you're actually downloading and presenting the binary image data instead of embedding HTML.
If you're going to be using Regex in AS3, then you absolutely must have the RegExr tool by grantskinner.com: http://gskinner.com/RegExr/desktop/.
Also, to get the data from capture group 2 we do this:
var imageTag:String = '<img src="https://blargh.com/displayTemplate?templateid=template1">'
var myHttpRegex:Regex = /\<img(.*?)"(.*?)"(.*)/;
var result:Object;
result = myHttpRegex.exec(imageTag);
if(result != null) {
var imgUrl:String = result[1];
}
Code is untested, but the concept is there.
i am trying to put context path for an image in HTML.<img src="/MyWeb/images/pageSetup.gif">
Here /MyWeb is the ContextPath which is hardcoded. How can i get dynamically.
i am using as <img src=contextPath+"/images/pageSetup.gif">but image is not displaying. Is there any option.
First of all, "Context path" is a term which is typically used in JSP/Servlet web applications, but you didn't mention anything about it. Your question history however confirms that you're using JSP/Servlet. In the future, you should be telling and tagging what server side language you're using, because "plain HTML" doesn't have a concept of "variables" and "dynamic generation" at all. It are server side languages like JSP which have the capability of maintaining and accessing variables and dyamically generating HTML. JavaScript can be used, but it has its limitations as it runs in webbrowser, not in webserver.
The question as you initially have will only confuse answerers and yield completly unexpected answers. With question tags you reach a specific target group. If you use alone the [html] tag, you will get answers which assume that you're using pure/plain HTML without any server side language.
Back to your question: you can use ${pageContext.request.contextPath} for this.
<img src="${pageContext.request.contextPath}/images/pageSetup.gif">

How to use relative paths without including the context root name?
Browser can't access/find relative resources like CSS, images and links when calling a Servlet which forwards to a JSP
You can't write JavaScript in the src attribute. To do what you want, try some code like this:
var img = new Image();
img.src = contextPath + "/images/pageSetup.gif";
document.getElementById('display').appendChild(img);
Here the target; the place where you want to display the image, is a div or span, with the id display.
Demo
With HTML, you'll have to take some extra traffic of producing an error, so you can replace the image, or you can send some traffic Google's way. Please do not use this:
<img src='notAnImage' onerror='this.src= contextPath + "/images/pageSetup.gif" '>
Demo
Do not use this.
You must use JavaScript for this.
First, have all images point to some dummy empty image on your domain while putting the real path as custom attribute:
<img src="empty.gif" real_src="/images/pageSetup.gif" />
Now have such JavaScript code in place to iterate over all the images and change their source to use the context path:
var contextPath = "/MyRealWeb";
window.onload = function() {
var images = document.getElementByTagName("img");
for (var i = 0; i < images.length; i++) {
var image = images[i];
var realSource = image.getAttribute("real_src") || "";
if (realSource.length > 0)
image.src = contextPath + realSource;
}
};
