【已解决】Win7更新导致WLW插件PictureManager不工作

C# crifan 783浏览 0评论

【问题】

最新刚更新了Win7,包括升级IE9到IE10。

但是却发现,原来在WLW(Windows Live Writer)中正常工作的,我自己写的插件:picturemanager却不工作了:

无法正常的检索WLW中插入的本地图片,并替换对应的图片地址了。

且会导致WLW死掉。

【解决过程】

1.看来还得去专门调试一把。

2.调试发现,原来之前的,正则表达式:

string imgP = @"<A\s+?(?<wholeHref>href=""file:///(?<hrefFullname>(?<hrefPath>.+?WindowsLiveWriter-?\d+/supfiles\w+/).+?(?<pointSuf>\.\w{3,4}))""(?<spaceTarget>\s+?target="".+?"")?).*?>.+?(?<titleStr>title=""?(?<title>[^""]+)""?)\s+(border=.+?\s+)?(?<altStr>alt=""?\k<title>""?)\s+src=""file:///(?<srcFullname>\k<hrefPath>(?<srcFilename>.+?)\k<pointSuf>)"".+?(?<widthHeight>width=(?<width>\d+)\s+?height=(?<height>\d+)).*?></A>";

Regex imgRx = new Regex(imgP, RegexOptions.Singleline | RegexOptions.IgnoreCase);

对于如下的html:

<P><A 
href="file:///C:/Users/CLi/AppData/Local/Temp/WindowsLiveWriter-1737927945/supfiles22CDBA/reply-for-use-a-record_thumb.png" 
target=_blank><IMG title="reply for use a record" 
style="BORDER-LEFT-WIDTH: 0px; BORDER-RIGHT-WIDTH: 0px; BACKGROUND-IMAGE: none; BORDER-BOTTOM-WIDTH: 0px; PADDING-TOP: 0px; PADDING-LEFT: 0px; DISPLAY: inline; PADDING-RIGHT: 0px; BORDER-TOP-WIDTH: 0px" 
border=0 alt="reply for use a record" 
src="file:///C:/Users/CLi/AppData/Local/Temp/WindowsLiveWriter-1737927945/supfiles22CDBA/reply-for-use-a-record_thumb.png" 
width=640 height=384></A></P>

<P><A 
href="file:///C:/Users/CLi/AppData/Local/Temp/WindowsLiveWriter-1737927945/supfiles22CDBA/use-80-port-to-login-hawk-cpanel2.png"><IMG 
title="use 80 port to login hawk cpanel" 
style="BORDER-LEFT-WIDTH: 0px; BORDER-RIGHT-WIDTH: 0px; BACKGROUND-IMAGE: none; BORDER-BOTTOM-WIDTH: 0px; PADDING-TOP: 0px; PADDING-LEFT: 0px; DISPLAY: inline; PADDING-RIGHT: 0px; BORDER-TOP-WIDTH: 0px" 
border=0 alt="use 80 port to login hawk cpanel" 
src="file:///C:/Users/CLi/AppData/Local/Temp/WindowsLiveWriter-1737927945/supfiles22CDBA/use-80-port-to-login-hawk-cpanel_thu.png" 
width=712 height=699></A></P>

是不匹配的,所以搜不到图片,无法实现地址替换了。

对应的原因是:

之前的情况是:style是在title之前

现在的情况变成了:style变到title之后了

所以之前的正则失效了。

然后看着如此复杂的正则,实在效率很低。

即使此处改正确了,等以后万一再变化一点点,则还是会出错。

所以,想办法换成之前所用的html的解析库:HtmlAgilityPack

3.后来都写好了完整的代码了:

        private void commonProcessFunction()
        {
            processedContent = curSelectCotent;

            //special is not thumb:

                            srcFileWidth = img.Width;
                            srcFileHeight = img.Height;

                            //here only scale according to width

                            //replace img html
                            //originalAImgHtml = originalAImgHtml.Replace(imgNode.OuterHtml, imgNode.WriteTo());
                        }

                        //do finnal replace
                        string newAImgHtml = aImgNode.WriteTo();
                        processedContent = processedContent.Replace(originalAImgHtml, newAImgHtml);
                    }
                    else 
                    {
                        //something wrong
                    }
                }
            }
        }

结果却是:

对于originalAImgHtml,实际上和本身的html不同:

即原先的html是:

<A 
href="file:///C:/Users/CLi/AppData/Local/Temp/WindowsLiveWriter-1737927945/supfilesFFB3D9/use-80-port-to-login-hawk-cpanel2.png"><IMG 
title="use 80 port to login hawk cpanel" 
style="BORDER-LEFT-WIDTH: 0px; BORDER-RIGHT-WIDTH: 0px; BACKGROUND-IMAGE: none; BORDER-BOTTOM-WIDTH: 0px; PADDING-TOP: 0px; PADDING-LEFT: 0px; DISPLAY: inline; PADDING-RIGHT: 0px; BORDER-TOP-WIDTH: 0px" 
border=0 alt="use 80 port to login hawk cpanel" 
src="file:///C:/Users/CLi/AppData/Local/Temp/WindowsLiveWriter-1737927945/supfilesFFB3D9/use-80-port-to-login-hawk-cpanel_thu.png" 
width=712 height=699></A>

而originalAImgHtml,即aImgNode.OuterHtml却是,处理后的:

<a href="file:///C:/Users/CLi/AppData/Local/Temp/WindowsLiveWriter-1737927945/supfilesFFB3D9/use-80-port-to-login-hawk-cpanel_thu.png" target="_blank"><img title="use 80 port to login hawk cpanel" style="BORDER-LEFT-WIDTH: 0px; BORDER-RIGHT-WIDTH: 0px; BACKGROUND-IMAGE: none; BORDER-BOTTOM-WIDTH: 0px; PADDING-TOP: 0px; PADDING-LEFT: 0px; DISPLAY: inline; PADDING-RIGHT: 0px; BORDER-TOP-WIDTH: 0px" border="0" alt="use 80 port to login hawk cpanel" src="file:///C:/Users/CLi/AppData/Local/Temp/WindowsLiveWriter-1737927945/supfilesFFB3D9/use-80-port-to-login-hawk-cpanel_thu.png" width="640" height="628"></a>

很明显,改变了:

标签的大小写

把一些属性,比如width和height的值,都加上了对应的引号

如此,导致:

虽然我们可以修改标签的各个属性值,且可以获得修改后的内容

但是由于最原始的originalAImgHtml,根本就不存在,所以

processedContent = processedContent.Replace(originalAImgHtml, newAImgHtml);

根本没有生效,所以导致我们此处的替换无效。

即,浪费了半天功夫,根本没有实现替换功能。

4.所以,看来还是只能换回原先的,用正则处理的了。

最后,为了匹配新的,style在boarder之后的,只是把:

string imgP = @"<A\s+?(?<wholeHref>href=""file:///(?<hrefFullname>(?<hrefPath>.+?WindowsLiveWriter-?\d+/supfiles\w+/).+?(?<pointSuf>\.\w{3,4}))""(?<spaceTarget>\s+?target="".+?"")?).*?>.+?(?<titleStr>title=""?(?<title>[^""]+)""?)\s+(border=.+?\s+)?(?<altStr>alt=""?\k<title>""?)\s+src=""file:///(?<srcFullname>\k<hrefPath>(?<srcFilename>.+?)\k<pointSuf>)"".+?(?<widthHeight>width=(?<width>\d+)\s+?height=(?<height>\d+)).*?></A>";

换为:

string imgP = @"<A\s+?(?<wholeHref>href=""file:///(?<hrefFullname>(?<hrefPath>.+?WindowsLiveWriter-?\d+/supfiles\w+/).+?(?<pointSuf>\.\w{3,4}))""(?<spaceTarget>\s+?target="".+?"")?).*?>.+?(?<titleStr>title=""?(?<title>[^""]+)""?)\s+.+?(border=.+?\s+)?(?<altStr>alt=""?\k<title>""?)\s+src=""file:///(?<srcFullname>\k<hrefPath>(?<srcFilename>.+?)\k<pointSuf>)"".+?(?<widthHeight>width=(?<width>\d+)\s+?height=(?<height>\d+)).*?></A>";

即可。

至此,目前至少还是可以继续使用了。

 

【总结】

一次普通的Win7的update,竟然会影响到到WLW,真是无语了。。。
