I need help replacing a string in a word document while keeping the formatting of the entire document. I'm using python-docx, after reading the documentation, it works with entire paragraphs, so I loose formatting like words that are in bold or italics.

Including the text to replace is in bold, and I would like to keep it that way. I'm using this code:. So if I implement it and want something like the paragraph containing the string to be replaced loses its formatting :. I posted this question even though I saw a few identical ones on herebecause none of those to my knowledge solved the issue.

There was one using a oodocx library, which I tried, but did not work. So I found a workaround. The code is very similar, but the logic is: when I find the paragraph that contains the string I wish to replace, add another loop using runs. Based on Alo 's answer and the fact the search text can be split over several runs, here's what worked for me to replace placeholder text in a template docx file. It checks all the document paragraphs and any table cell contents for the placeholders.

Once the search text is found in a paragraph it loops through it's runs identifying which runs contains the partial text of the search text, after which it inserts the replacement text in the first run then blanks out the remaining search text characters in the remaining runs.

I hope this helps someone. Here's the gist if anyone wants to improve it. Edit: I have subsequently discovered python-docx-template which allows jinja2 style templating within a docx template.

You could try using indices. Ex for p in range len doc. I think this gives the same output I'm currently getting. The file keeps its formatting, except the paragraph that contains the string to be replaced.

Please correct me if I'm wrong. Text formatting is not saved when using assignment. All run-level formatting, such as bold or italic, is removed. Active Oldest Votes.

The thing is that if you find the word you want to replace in a line, you will still replace the whole line by doing this instead of just the one word you want to replace. It's still better than replacing the whole paragraph though.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

I've been doing a lot of searching for a method to find and replace text in a docx file with little luck. I've tried the docx module and could not get that to work. Eventually I worked out the method described below using the zipfile module and replacing the document.

For this to work you need a template document docx with the text you want to replace as unique strings that could not possibly match any other existing or future text in the document eg.

My question is what's wrong with this method? I'm pretty new to this stuff, so I feel someone else should have figured this out already. Which leads me to believe there is something very wrong with this approach. But it works! What am I missing here? Step 1 Prepare a Python dictionary of the text strings you want to replace as keys and the new text as items eg.

Step 4 Extract the document. Step 5 Use a for loop to replace all of the text defined in your dictionary in the xml text string with your new text.

Sometimes, Word does strange things. You should try to remove the text and rewrite it in one strokeeg without editing the text in the middle. This happens quite often because of language support : word splits words when he thinks that one word is of one specific language, and may do so between words, that will split the words into multiple tags. Only problem with your solution is that you have to write everything in one stroke, which isn't the most user-friendly.

It is very easy to create a docx file by python-docx, but I like to search some specific words and count the number it occurs, how can I do in python-docx. If your document included tables you wanted to search as well, you would need to look there too, something like:. There can be a recursion involved, not sure how frequent it is in practice, but structurally there's nothing preventing a paragraph within a table from itself containing a table, which contains paragraphs that can contain a table, etc.

Right now python-docx only detects top-level tables, so that might be something to watch out for. I'm sure it will be good to have something that allows search and replace operations. I'm not quite sure what the search operation would return, since there's no concept so far of a 'cursor' location nor is there a concept of a word or phrase, only paragraphs and runs, which of course wouldn't always match up on a particular word.

But I'll leave it here for more noodling when we get to this in the backlog. Having some trouble along these same lines though. This spits out an attribute error when trying to update the text. The error. I'm okay at python but couldn't really see any way to fix this looking at text. There's actually no way yet to do what you're trying to accomplish here.

I'm working on a translation app and I would like to take a docx file and create a new one with the same styles and runs, but having the text in a different language.

Is there any way I could do this? I read that changing paragraph's text, removes all styles and runs from it! The other approach I tried was using runs object to create my new file. The problem with this is that I have to translate the text of each run separate and the final text doesn't make any sense.

Again, not an option for me, because it's a translation app and I need my final text to make sense hahaha. KGomes27 Could you solve your problem? If yes, could you please share? I am trying to deal with similar problem as well.

UttamDwivedi Hi, I wasn't able to find a good enough solution. What I did at the moment was follow David's recommendation to at least get some of the original paragraph's styles onto the new paragraph. So "read" all the runs in a paragraph, re-arrange them during translation, and build the new paragraph in the new document out of the re-arranged runs.

Think of each run within a paragraph as an object containing text and formatting. Whatever words were highlighted, underlined, or whateverwould still want to be highlighted in the same way in the new run position within the paragraph. So during the translation process, you're not re-ordering just text, but text-and-formatting, which is to say, runs.

You might need to break some of your runs into multiple parts because of the subtleties of different word orders in different languages, but you can figure that out and carry the formatting along with the words into the multiple new parts.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The opendocx function is part of the legacy API. The documentation is for the new version. The legacy version has no documentation to speak of. Neither reading nor writing hyperlinks are supported in the current version. That capability is on the roadmap, and the project is under active development.

It turns out to be quite a broad API because Word has so much functionality. So we'll get to it, but probably not in the next month unless someone decides to focus on that aspect and contribute it.
