Find a specific Table (after a bookmark) in open xml

问题

I have a document with multiple tables in it. I need to fill some of those tables. The problem im having is how do i locate them? I can interate through them

var doc = document.MainDocumentPart.Document;
var tables= doc.Body.Elements< Table >();

But how do i find a specific table? The table can change so i cant rely on the order. I was thinking of placing a bookmark ahead of the specific table and just locate the first table after the bookmark, but i have failed to find out how to do that...

So, how do one find a specific table in a document?

If there is a better way of doing it please let me know.

回答1:

Give the tables captions.

First in Word, create the tables, and right click one of them, Table Properties, Alt Text, fill in the Title box, save, close.

Now in OpenXML, find the table with specific captions.

IEnumerable<TableProperties> tableProperties = bd.Descendants<TableProperties>().Where(tp => tp.TableCaption != null);
foreach(TableProperties tProp in tableProperties)
{
    if(tProp.TableCaption.Val.Equals("myCaption")) // see comment, this is actually StringValue
    {
        // do something for table with myCaption
        Table table = (Table) tProp.Parent;
    }
}

A bit more elegant solution to this, using bookmarkstart as a locator would be

BookmarkStart bookmark = YourBookMarkStart;
OpenXmlElement elem = bookmark.First().Parent;
//isolate tabel
while (!(elem is DocumentFormat.OpenXml.Wordprocessing.Table))
    elem = elem.Parent;
var table = elem; //found

I found a solution. It's not the prettiest solution i have come up with but it seems to work. At least on the documents that i have tried.

I create my table. Insert a Bookmark anywhere in the table and then find the bookmark.

var bookmarkStart = doc.Body.Descendants<BookmarkStart>().Where(r => r.Name == "tableBookmark");
if (bookmarkStart != null)
{
    var test  = bookmarkStart.First().Parent.Parent.Parent.Parent;
    if (test.GetType() == typeof (DocumentFormat.OpenXml.Wordprocessing.Table))
        myTable = (Table)test;
}

Please feel free to give me a better solution!!! :) For instance I'm probably going to make a recursive method that finds the tables instead of using Parent.Parent.Parent.Parent
