查找/替换在文件中与REBOL连接的字符串。

I have an HTML page, and I need to replace a couple of lines in it. However, using replace can't seem to find anything bigger than a single line.

我有一个HTML页面，我需要替换其中的几行。然而，使用replace似乎找不到比单行更大的东西。

This is what I would like to replace (there are multiple instances of it in the page):

这是我想替换的(页面中有多个实例):

....
<div class="logo">
    <img src="resources/logo.svg" />
    <span>e</span>
    <span class="text">Market</span>
</div>
...

Here's the code I am trying, but it doesn't work:

这是我正在尝试的代码，但它不起作用:

index-html: read %index.html    

logo-div: {<div class="logo">
<img src="resources/logo.svg" />
<span>e</span>
<span class="text">Market</span>
</div>}

new-div: {...}

out: replace/all index-html logo-div new-div

write %index.html out

Including ^/ in my logo-div string to denote the newlines doesn't help.

包括^ /在我logo-div字符串表示换行不帮助。

How can I find this entire string?

我怎么能找到这整条线?

(I am using Rebol2, but I assume the functionality will be the same or very similar in Rebol3.)

(我正在使用Rebol2，但我假设Rebol3的功能是相同的或非常相似的。)

I'm not sure about replace but this is a good opportunity for parse to work well:

我不太确定是否要替换，但这是一个很好的机会，可以让parse很好地工作:

index-html: read %index.html
out: copy ""
new-div: "..."

;;parse rules

title: [
    {<div class="logo">} thru {</div>} (append out new-div) ;;appends replacement when it finds that class
]

rule: [
    some [
        title |
        copy char skip (append out char)  ;;copies every other char char
    ]
]

parse index-html rule

write %index.html out

Don't have the index file, but this should work. Take some time to carefully study string parsing. It is very powerful.

不要有索引文件，但是这个应该可以工作。花些时间仔细研究字符串解析。它是非常强大的。

I suspect the issue you are facing is that of the variable number of spaces between elements. If you can trim out the whitespace, replace should work:

我怀疑您所面临的问题是元素之间的空间的可变数量。如果你能减少空白，替换应该工作:

>> data: {
{    line 1     
{    line 2  
{    line 3
{    line 4   
{    <div>
{    line d1   
{    line d2
{    </div>
{    line 5    
{    line 6                   
{    }
== {
line 1     
line 2  
line 3
line 4   
<div>
line d1   
line d2
</div>
line 5    
line 6                   
}
old-div: {                
{    <div>
{    line d1   
{    line d2
{    </div>
{    }
== {
<div>
line d1   
line d2
</div>
}
>> new-div: {
{    <div>new line d1^/new line d2</div>
{    }
== "^/<div>new line d1^/new line d2</div>^/"
>> replace/all trim/all data trim/all old-div new-div
== {line1line2line3line4
<div>new line d1
new line d2</div>
line5line6}
>> data
== {line1line2line3line4
<div>new line d1
new line d2</div>
line5line6}

If you want to retain the HTML indentation, then parse as suggested by kealist would probably be the best option.

如果您希望保留HTML缩进，那么按键符建议进行解析可能是最好的选择。
