Also, share what version of Python, OS and editor you are using.

FYI, this is a text only list, images of attachments will be filtered.

[Tutor] remove ^ in field

[PERRAS Pierre]

Hi,

Sending lab result in HL7.  In the following example, I want everything 
(PATNUMBER~000925015-001) after 000925015 in PID3-1.  I want also to remove 
 everything (^^L) after PID5-2.

This is a text only list so attachments tend to get stripped off.

We need a lot more information I'm afraid.

What are you using to "reopen" the file? Are you using a text
editor or an IDE (like IDLE or eclipse?).

Show us the full error text and your code - just paste
it into the mail message.

It also might help to tell us the Python version and the OS.

You are preonbably better using your parseers escape/unescape
facilities. Simple string replacement is notioriously hard to
get right.

Define separate? There are several options in the standard library.
All will be more effective than trying to do it by hand.
And libxml2dom is not one of them (at least I've never
seen it before) so you appear to be breaking your own rules?

You can get the same effect with

import libxml2dom as ql

You may have over-simplified a tad, it has become fairly
meaningless to us - what are 'a' and 'tpath'?

Re: [Tutor] please help me modify this code so that I can utilize raw_input

You don't need to modify your code you just need ton write a function
that reads a list from the user. Notice that this can e done by either
repeatedly asking the user to input values until they are done or by
reading a string containing the values and converting the string to a
list of numbers.

I do wish teachers would not ask students to reinvent the wheel.
Python already has a perfectly good sum() function.
And both problems become trivial if using functools.reduce()

Incidentally, notice that the assignment asks you to *return* the
results not print them. This is good practice, keep the printing
separate from the calculation. You can then print the result,
if you wish, with

print( sum([]) )

I would like to modify this code so that instead of me calling the function
with the list as shown [1,2,3,4], the user inputs the list with raw_input.

Thanks in advance

[Tutor] xpath - html entities issue --

[bruce]

Hi.

Just realized I might have a prob with testing a crawl.

I get a page of data via a basic curl. The returned data is
html/charset-utf-8.

I did a quick replace ('','&') and it replaced the '' as desired.
So the content only had '&' in it..

I then did a parseString/xpath to extract what I wanted, and realized I
have '' as representative of the '&' in the returned xpath content.

My issue, is there a way/method/etc, to only return the actual char, not
the html entiy ()

I can provide a more comprehensive chunk of code, but minimized the post to
get to the heart of the issue. Also, I'd prefer not to use a sep parse lib.


code chunk

import libxml2dom

q1=libxml2dom

s2= q1.parseString(a.toString().strip(), html=1)
tt=s2.xpath(tpath)

tt=tt[0].toString().strip()
print "tit "+tt

-


the content of a.toString() (shortened)
.
.
.
 

Organization
Development & Change
Edition: 10th



.
.
.

the xpath results are



Organization
Development  Change
Edition: 10th



As you can see.. in the results of the xpath (toString())
 the & --> 

I'm wondering if there's a process that can be used within the toString()
or do you really have to wrap each xpath/toString with a unescape() kind of
process to convert htmlentities to the requisite chars.

Thanks

Re: [Tutor] Need help

[niraj pandey]

Attaching two snapshots here.

In first snapshot (1.png) I have the label windows without the values and
in second window (2.png) every label have some value.
I want to put these values in front of every label. I have already stored
these values in a variable.

Thanks
