Remove all rows of lines between two strings from xml file using python

Remove all rows of lines between two strings from xml file using python

Any of those help Use a SAX parser such as xml.sax. This gives you callbacks as it scans the XML file for each of the various xml tags or 'events' (ie opening a tag, closing a tag, seeing an attribute, seeing some data, etc). Keep track of whether you are in part of the XML file you do or do not want to keep (or delete) as you get these callbacks. Stream the data into a new file if you are in "keeping" mode, and don't otherwise.
When dealing with XML, always use a proper parser of some sort. The dangers of trying to use regexes or otherwise trying to do it yourself have been well documented.

fixed the issue. Will look into that further I am using a template to create multiple .txt files. Some files will have empty values, so I want to remove the resulting empty lines: , The function you want is list.pop(index).
code :
# assuming you have the contents read from the file split into this list:
lines = content.splitlines()

indicestoremove=[]
for index in range (2,6): # or whatever range of lines you want to trim - 
                          # remember indices start from 0 for the first line
    if lines[index] == '':
        indicestoremove.append(index)

# remove in reverse order, as pop() changes the index of items later in the list
for index in sorted(indicestoremove, reverse=True):
    lines.pop(index)

f = open('filename')
for line in lines:
  f.write("%s\n" % line)

wish helps you
The short and incomplete answer is that you missed to specify the /L switch of findstr, which forces to do literal searches. Without it, the first search string determines whether literal search or regular expression mode is chosen. Since there are file names included in the search strings, which hold a period to separate the base name from the name extension, which is also a meta-character in regular expression mode, findstr selects that mode most probably.

wish helps you I have put together a script which reads a text file as below, , Add an additional write(line) when "*ELEMENT" is found in line.

# init conditions
writing = False

with open('shell.txt', 'r') as oldfile, open('new_shell.txt', 'w') as newfile:
    for line in oldfile:
        if writing:
            if "*NODE" in line:
                writing = False
            else:
                newfile.write(line)
        elif "*ELEMENT" in line:
            newfile.write(line)
            writing = True

newfile.write
